Linear Mixed-Effects Models with R review for 2025

In our review of this course, we try to help you answer all of your most important questions about Linear Mixed-Effects Models with R as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use LMMWR as an abbreviation of the course name?

During our Linear Mixed-Effects Models with R course review, you might sometimes see us refer to it as LMMWR for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and LMMWR is simpler and easier for reviewing purposes

The full course name is 34 characters long, including blanks, while LMMWR is 5 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 29 characters every time we use LMMWR.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to LMMWR throughout the remainder of this review.

Is the Linear Mixed-Effects Models with R course for you?

To determine whether Geoffrey Hubona, Ph.D.’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what Geoffrey Hubona, Ph.D.’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that Geoffrey Hubona, Ph.D. chose for the course, “Linear Mixed-Effects Models with R”, as well as its subtitle: “Learn how to specify, fit, interpret, evaluate and compare estimated parameters with linear mixed-effects models in R.”.

This combo of title and subtitle should be enough to communicate the purpose of the training if Geoffrey Hubona, Ph.D. is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what LMMWR is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means Geoffrey Hubona, Ph.D. hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what Linear Mixed-Effects Models with R is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of Geoffrey Hubona, Ph.D.’s official description of LMMWR

Linear Mixed-Effects Models with R is a 7-session course that teaches the requisite knowledge and skills necessary to fit, interpret and evaluate the estimated parameters of linear mixed-effects models using R software. Alternatively referred to as nested, hierarchical, longitudinal, repeated measures, or temporal and spatial pseudo-replications, linear mixed-effects models are a form of least-squares model-fitting procedures. They are typically characterized by two (or more) sources of variance, and thus have multiple correlational structures among the predictor independent variables, which affect their estimated effects, or relationships, with the predicted dependent variables. These multiple sources of variance and correlational structures must be taken into account in estimating the “fit” and parameters for linear mixed-effects models.

The structure of mixed-effects models may be additive, or non-linear, or exponential or binomial, or assume various other ‘families’ of modeling relationships with the predicted variables. However, in this “hands-on” course, coverage is restricted to linear mixed-effects models, and especially, how to: (1) choose an appropriate linear model; (2) represent that model in R; (3) estimate the model; (4) compare (if needed), interpret and report the results; and (5) validate the model and the model assumptions. Additionally, the course explains the fitting of different correlational structures to both temporal, and spatial, pseudo-replicated models to appropriately adjust for the lack of independence among the error terms. The course does address the relevant statistical concepts, but mainly focuses on implementing mixed-effects models in R with ample R scripts, ‘real’ data sets, and live demonstrations. No prior experience with R is necessary to successfully complete the course as the first entire course section consists of a “hands-on” primer for executing statistical commands and scripts using R.

Does LMMWR pass the 30 Seconds Test?

You can read a lot more about Linear Mixed-Effects Models with R on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, Geoffrey Hubona, Ph.D. has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other Teaching & Academics classes that are more clearly defined and more tailored to your specific interests.

Did Linear Mixed-Effects Models with R appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with LMMWR above, what is your gut reaction to this Teaching & Academics course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did Geoffrey Hubona, Ph.D. do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, Geoffrey Hubona, Ph.D.’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other Teaching & Academics courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does Geoffrey Hubona, Ph.D. sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the LMMWR course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, Geoffrey Hubona, Ph.D.’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including Geoffrey Hubona, Ph.D., have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from Geoffrey Hubona, Ph.D.’s Udemy bio

Dr. Geoffrey Hubona held full-time tenure-track, and tenured, assistant and associate professor faculty positions at 3 major state universities in the Eastern United States from 1993-2010. In these positions, he taught dozens of various statistics, business information systems, and computer science courses to undergraduate, master’s and Ph.D. students. He earned a Ph.D. in Business Administration (Information Systems and Computer Science) from the University of South Florida (USF) in Tampa, FL (1993); an MA in Economics (1990), also from USF; an MBA in Finance (1979) from George Mason University in Fairfax, VA; and a BA in Psychology (1972) from the University of Virginia in Charlottesville, VA. He was a full-time assistant professor at the University of Maryland Baltimore County (1993-1996) in Catonsville, MD; a tenured associate professor in the department of Information Systems in the Business College at Virginia Commonwealth University (1996-2001) in Richmond, VA; and an associate professor in the CIS department of the Robinson College of Business at Georgia State University (2001-2010). He is the founder of the Georgia R School (2010-2014) and of R-Courseware (2014-Present), online educational organizations that teach research methods and quantitative analysis techniques. These research methods techniques include linear and non-linear modeling, multivariate methods, data mining, programming and simulation, and structural equation modeling and partial least squares (PLS) path modeling. Dr. Hubona is an expert of the analytical, open-source R software suite and of various PLS path modeling software packages, including SmartPLS. He has published dozens of research articles that explain and use these techniques for the analysis of data, and, with software co-development partner Dean Lim, has created a popular cloud-based PLS software application, PLS-GUI.

What did you think about Geoffrey Hubona, Ph.D. after reading just the first few lines of the bio above?

After reading just the first few lines about Geoffrey Hubona, Ph.D., did it make you more or less interested in taking the LMMWR course?

And did it make you feel like Geoffrey Hubona, Ph.D. was more or less credible and qualified to teach Linear Mixed-Effects Models with R?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this Teaching & Academics course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the LMMWR lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Linear Mixed-Effects Models with R course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the LMMWR course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing Geoffrey Hubona, Ph.D.’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Linear Mixed-Effects Models with R, as well as the course’s subtitle, Learn how to specify, fit, interpret, evaluate and compare estimated parameters with linear mixed-effects models in R..

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that LMMWR is potentially a good, useful course for you, and you can have more confidence in Geoffrey Hubona, Ph.D.’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from Geoffrey Hubona, Ph.D. that you enjoyed?

Have you already learned something from Geoffrey Hubona, Ph.D. that you valued or enjoyed?

For example, does the Linear Mixed-Effects Models with R training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any LMMWR lessons for free, have you perhaps watched a YouTube video by Geoffrey Hubona, Ph.D., or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of Geoffrey Hubona, Ph.D.’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with Geoffrey Hubona, Ph.D.’s teaching methods, and the more you enjoy them, the more likely it is that Linear Mixed-Effects Models with R will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from Geoffrey Hubona, Ph.D. before purchasing this course, since it’s one of the best ways to determine whether LMMWR will be helpful for you.)

Are “Linear Mixed-Effects Models with R” reviews generally positive?

On the bottom of the LMMWR page, you can read student reviews of the class.

Prior to August 19, 2025, there were 490 students enrolled, 176 reviews / ratings, and it was overall rated 3.5 out of 5.

Obviously, the more highly other students rate LMMWR the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the LMMWR reviews to get an overall sense of them. You don’t have to read each one!

Is Geoffrey Hubona, Ph.D. responsive to student questions in the LMMWR training?

You can see what other students have to say about this in their LMMWR reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send Geoffrey Hubona, Ph.D. a message through this system quite easily, even if you haven’t bought LMMWR yet.

For example, you could say, “Hi, and I came across LMMWR while looking at Teaching & Academics courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Linear Mixed-Effects Models with R on your own, online?

This is a big one, because Linear Mixed-Effects Models with R is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Linear Mixed-Effects Models with R.

Yes, you will be able to interact with the students and the teacher, Geoffrey Hubona, Ph.D., online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of LMMWR make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Linear Mixed-Effects Models with R training that looks something like this:

• The purpose of LMMWR can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• Geoffrey Hubona, Ph.D. is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other LMMWR students have great things to say about the program

Other benefits include:

• You get to go through LMMWR at your own pace
• You join a community of 490 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that LMMWR would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford LMMWR?

Can you comfortably afford the cost of Linear Mixed-Effects Models with R?

This is an important question to answer, because even if you think LMMWR sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 19, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on LMMWR with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on Linear Mixed-Effects Models with R?

By far, the easiest way to get the best and biggest discount on this course is to use the Linear Mixed-Effects Models with R discount code link at the top of this page.

It will instantly give you the best coupon code we could find for Geoffrey Hubona, Ph.D.’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best LMMWR course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting LMMWR for a better price, but also with any other Geoffrey Hubona, Ph.D. Udemy course that you’d like to get for cheaper.

How can Google help you get a LMMWR discount?

To use this method, do a Google search for the LMMWR training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Linear Mixed-Effects Models with R promo code” or “Linear Mixed-Effects Models with R udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with Geoffrey Hubona, Ph.D.’s name and see what happens.

For example, you might do a Google search for “Geoffrey Hubona, Ph.D. Udemy coupons” or “Geoffrey Hubona, Ph.D. course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Linear Mixed-Effects Models with R coupons” rather than “Geoffrey Hubona, Ph.D. coupons”.

How can a Udemy sale get you LMMWR for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get LMMWR for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if Geoffrey Hubona, Ph.D. decides not to participate in the site wide sale, then you won’t get a discount on LMMWR, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the LMMWR course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a LMMWR discount from Geoffrey Hubona, Ph.D.?

If you’re really serious about getting “Linear Mixed-Effects Models with R” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Geoffrey Hubona, Ph.D., instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get Geoffrey Hubona, Ph.D.’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Linear Mixed-Effects Models with R. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join Geoffrey Hubona, Ph.D.’s mailing list, if you can find it, and then you hope that at some time LMMWR will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get LMMWR for free?

Of course, the best possible price for the LMMWR training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that Geoffrey Hubona, Ph.D. has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Linear Mixed-Effects Models with R free coupon” or “Linear Mixed-Effects Models with R 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even Geoffrey Hubona, Ph.D. has offered free coupons for LMMWR in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a LMMWR free download?

It’s important to understand that there’s a difference between getting full access to the LMMWR training for free legally with a free coupon code vs. finding a way to download LMMWR illegally.

If you really want to go the download route, you can do a google search for something like “Linear Mixed-Effects Models with R download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Linear Mixed-Effects Models with R free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, Geoffrey Hubona, Ph.D. created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 490 students enrolled in the program.

Can you get a refund on Linear Mixed-Effects Models with R if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the LMMWR training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into Geoffrey Hubona, Ph.D.’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on LMMWR no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the LMMWR training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing Geoffrey Hubona, Ph.D. could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing LMMWR and not liking it, since you can always get your money back.

What is OCP’s overall rating of Linear Mixed-Effects Models with R?

During this LMMWR review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the LMMWR training, the instructor, Geoffrey Hubona, Ph.D., and reading what other students have said about this program, we give it an overall rating of 4 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.
