## À propos du cours

This course introduces the Bayesian approach to statistics, starting with the concept of probability and moving to the analysis of data. We will learn about the philosophy of the Bayesian approach as well as how to implement it for common types of data. We will compare the Bayesian approach to the more commonly-taught Frequentist approach, and see some of the benefits of the Bayesian approach. In particular, the Bayesian approach allows for better accounting of uncertainty, results that have more intuitive and interpretable meaning, and more explicit statements of assumptions. This course combines lecture videos, computer demonstrations, readings, exercises, and discussion boards to create an active learning experience. For computing, you have the choice of using Microsoft Excel or the open-source, freely available statistical package R, with equivalent content for both options. The lectures provide some of the basic mathematical development as well as explanations of philosophy and interpretation. Completion of this course will give you an understanding of the concepts of the Bayesian approach, understanding the key differences between Bayesian and Frequentist approaches, and the ability to do basic data analyses....

Good intro to Bayesian Statistics. Covers the basic concepts. Workload is reasonable and quizzes/exercises are helpful. Could include more exercises and additional backgroung/future reading materials.

An excellent course with some good hands on exercises in both R and excel. Not for the faint of heart mathematically speaking, assumes a competent understanding of statistics and probability going in

So, I really wanted to LOVE this class, but instead I found that I merely liked it, and want to use this review as a way to explain why. WHAT I LIKE ABOUT THE CLASS: The material is sufficient for the topic at hand, and is structured in an appropriate way. If you work through everything you'll have a decent grasp of exactly what the class is meant to be about. It's also pretty well paced. WHAT I DIDN'T LIKE ABOUT THE CLASS: Dr. Lee usually rushes through or skips discussions what concepts mean before formalizing them mathematically. As a result it's very easy to make progress through the class without a good feeling that you actually "get" what Bayesian statistics is really about. Too many of these videos are him chopping wood through the mathematical jingo, when the material DESPERATELY needed a 3-5 minute introductory video about what concepts actually mean or how to think about them. I remember telling my girlfriend during the middle of the class that I found it frustrating because I was progressing through it quickly, and getting the quizzes right, but lacked a good intuition for how to think about Bayesian statistics. So Dr. Lee......work on those presentation skills! Think deeply about how to communicate the essentials of the concepts in each lesson, and THEN start pounding away on the whiteboard!

I don't find that the lectures do a good job of relating the material to real world usage. To much focus on equations and too little on the why.

I felt like I just did a lot of calculations. The course was better in the beginning, as I felt the professor actually explained what and why were were doing what we were doing. By the middle of the course, however, I felt that the professor just jotted down equations and went really quickly. I don't actually understand why I was doing the calculations that I was doing.

Almost no intuition is given. I really got bored while watching the formulas to be written on the board without giving real meaning behind them. I would not have taken this course I was aware of these.

Herbert Lee is teaching by seeing books and write lots of equations doesn't explain how theory and equations related to real world applications. Its more like class room lessons , not like something that can be applied to real world scenarios.

The instructor doesn't do a good job at teaching. He throws so many formulas at you without explaining any of them. The course is purely based on memorization not understanding the concepts. I have been using other online classes to be able to understand this class.

This course gives an introduction to the theoretical basics of Bayesian statistics. Before taking this class, I had a very confused view of the whole Frequentist vs Bayesian "debate". I understand now that Bayesian statistics is really about attaching uncertainties to beliefs and producing a clear definition of this uncertainty (especially through the notion of credible intervals).

The course really focusses on theory. I recommend knowing a bit of basic stats concepts before taking the class, such as Bayes' Theorem, basic discrete and continuous distributions, and confidence intervals. If you are not experienced with these, be aware that you will likely need to read-up on them throughout the course. R is used, but the usage is so simple that you should not shy away due to a lack of R experience.

I really have no complaints about the course. After completing it, you should understand the differences between Bayesian and Frequentist approaches. You will also understand a lot of terminology that gets thrown around in data science these days (priors, posteriors, credible intervals).

If you already know everything about the topic and just forgot some little things or you are very strong in calculus, this may be a nice refresher. Otherwise, not very useful. Really dense and little explanation. I liked the Youtube MIT course on Probability (it includes Bayesian Statistics) much more, since it has good explanation of the concepts.

A good MATHEMATICAL introduction to Bayesian Statistics. I read some of the negative reviews and they claim to have many formulas, well, that was exactly what I was looking because after watching some PyCon Videos about Bayesian Statistics I understood the code to solve the problem but not really why that code works or how.

This course may be frustrating for those with no prior introduction to Bayesian statistics, I recommend to take this course after seeing some videos from the Scipy, PyData and PyCon conferences regarding this topic.

What I like about this course is that it goes into mathematical details and gives students with no or very limited prior knowledge about Bayesian statistics (even though some familiarity with general statistics is required) a pretty comprehensive introduction. Having almost completed the course, in retrospective I can say that I have learned a lot and also gained some intuition about Bayesian Statistics. However, here comes the problem: I think that I learned most when I resorted to textbooks or YouTube after not having understood the content provided by the instructor. The instructor does not try at all to provide intuition, he rather reads formulas from his notes and then writes them down. Of course, a topic this complicated requires that students do some additional work. However, Mr. Lee is definitely not a good teacher, and worse, he does not even try to be one – even a good teacher would not be able to convey a topic like exponential distribution and its usage in Bayesian statistics in just 4 minutes. In short: very good structure of the course, but pretty bad teaching style.

I get lost a bit too often.

The teacher sometimes explains easy concepts and omits the difficult ones (e.g. exponential distribution is explained as "for example if you are waiting for a bus that comes every ten minutes" and then he tells you how to compute expected value and moves on, but he does not say WHAT IT MEANS - is it the probability that I will meet an oncoming bus? is it probability of waiting ten minutes for the bus? is it the average waiting time? is it average number of buses that come every hour? - but there is detailed explanation of what A squared means in lesson two (!))

The teacher often makes me confused as to where he got the numbers he is plugging in the formula or what answer the formula gives.

But I take it as a challenge and I intend to finish the course despite all of that. Sometimes it is fun to decipher the mystic equations. And maybe it is me, maybe I was not born to be a statistician. Maybe there are people that find this stuff easy and understand it right away.

I really like the quizes. They are HARD.

One last thing: Wearing white shirt and using white marker makes it impossible to read what he writes. But I take it is part of the challenge ;-)

When doing the quiz for Lesson 2, Week 1, I first failed, then I used the hints provided to do the appropriate calculations, however the numbers I obtain are considered incorrect, and I cankot pass the quiz although I checked the calculations million times and I know I am correct. There should be a demonstration of how the correct answer is obtained, simpke hints are not enough. Although I was super excited about learning Bayesian statistics, now I am forced to quit as it looks I will never be able to complete the course. The course ended up being useless and frustrating. This is truly unfortunate

Very useful to get an initial understanding of bayesian statistics. Recommends using R or excel but possible to use python using statsmodels.api, scipy, numpy and pandas tools

There should be more focus on understanding the equations. The R and excel videos were incredibly blurry.

This was a fantastic introduction to Bayesian statistics. Professor Lee is an excellent lecturer, with a comfortable, almost conversational style that I found easy to follow and stay focused on. The course itself is very well organized, introducing key concepts and then immediately providing examples that helped me internalize the concepts they pertained to. Quizzes were low pressure, straightforward applications of the lectures that served the purpose of allowing me to immediately apply what I had just learned.

This course introduces the key difference between the Frequentist approach and the Bayesian approach on both discrete and continuous data. The instructor is capable of connecting the dots between the intuition of the theories, the mathematical formulation, and the real-life application. One thing I would suggest is to provide external links to each unfamiliar terminologies mentioned in the videos.

This is a math course. It has good quality, it is rigorous and educational. It presents the mathematical framework of the Bayesian statistics. I like it when the math of the subject is explained well, as done in this course, rather than "I don't want to get in to the math", or "it is beyond the scope of this course", which you often see in online courses.

This is an excellent course for beginners attempting to understand the Bayesian framework—one of the best I've seen on Coursera. I would only suggest the professor use Cmd + C and Cmd + V for R lectures. It pains me to watch him driving the cursor to click to copy-paste.

This was a great course. My only critique is that it is a bit rushed during the last week. But the first three weeks are excellent. Please more of this and please combine the three Bayesian Statistics courses into a specialization.

This course makes a lot of details clear to me. Thanks professor for this great course.

I still have one question, is the professor writing on a transparent board in inverse pattern? The technique is amazing!

Very concise and helpful for an intro to Bayesian statistics. Good level of difficulty to encourage learning. This well prepares further study of more advanced topics such as MCMC and more.

Overall, an informative and useful introduction to Bayesian statistics. I would have preferred if the examples in the lessons in which prior and posterior were introduced went beyond the "coin flipping" binomial examples. I've taken a number of stats classes, and while coin flipping is to stats as "hello world" is to computer programming, I feel that students would grasp the importance of Bayesian inference much better if more realistic examples were used. Related to this, while the theory is important and understanding how to integrate the likelihoods is useful for grasping key concepts, nobody in practice really does this. You're going to use a programming language like R or some kind of stats package. More focus on these would be good.
