This course describes Bayesian statistics, in which one's inferences about parameters or hypotheses are updated as evidence accumulates. You will learn to use Bayes’ rule to transform prior probabilities into posterior probabilities, and be introduced to the underlying theory and perspective of the Bayesian paradigm. The course will apply Bayesian methods to several practical problems, to show end-to-end Bayesian analyses that move from framing the question to building models to eliciting prior probabilities to implementing in R (free statistical software) the final posterior distribution. Additionally, the course will introduce credible regions, Bayesian comparisons of means and proportions, Bayesian regression and inference using multiple models, and discussion of Bayesian prediction.
We assume learners in this course have background knowledge equivalent to what is covered in the earlier three courses in this specialization: "Introduction to Probability and Data," "Inferential Statistics," and "Linear Regression and Modeling."...

Great course. Difficult to apprehend sometimes as the Frequentist paradigm is learned first but once you get it, it is really amazing to see the believe update in action with data.

I like this course a lot. Explanations are clear and much of the (unnecessarily heavyweight) maths is glossed over. I particularly liked the sections on Bayesian model selection.

I find the teaching a bit unclear. I still don't sure I understand how to use Bayesianinference on problems I encounter in my work.

The last two weeks are way too hard to follow and could provide more practical examples instead of focusing on mathematical theory and formulas. That would make more sense to this course when compared to the content of the previous ones in this specialization.

The materials and response from the organization are unavailable for a while and never get an answer

Unfortunately, for me, this course did not live up to my expectations in comparison to the previous 3 courses I took as part of the Statistics with R specialisation. I gave the previous 3 a full 5 stars each.

The problems I had with this course was not that my statistics knowledge was lacking or that I found it difficult. The problems were due to the robotic delivery of the material. Specially towards the end of the course. It is very clear that the instructors have a great depth of knowledge which is incompatible with the robotic delivery structure currently in place.

For example, if you use a particular technique, even if it was introduced earlier, all it takes is a brief 2-10 second statement to re-iterate. This encourages the delivery of the material to be a hybrid of both written text the instructors are reading from, as well as a more informal aura of discussion. A guideline is: 'Can you get someone off the street to read the material you wrote to the screen?'. The more this statement is false, the more amazing your course is.

Another issue I had was that the accompanying material was immense. Am I paying a subscription to read books and passages in order to understand the material? This point is also prevalent in the forums where it was raised multiple times. These books and supplementary material would be largely not required if simple commentary was in place in the videos.

E.g. We are applying a 'BIC' prior. What does this mean? Up to this point we are used to applying priors that are distributions. This means that we are approximating the posterior probabilities of the models using the maximisation of their log-likelihoods which turns out to be easier to calculate than the posterior distributions. However, as the model space grows (>25 parameters), we may need to rely on a sampling technique, these techniques which rely on posterior probabilities to traverse the model space. If I were to say this, it would take me 10 seconds but would provide so much information to the learner.

In summary, I could have read a lot of the presented material here from a text book and found it clearer which wasn't the case in the previous 3 courses. The resources were helpful and focused on interesting points. I loved the interviews at the end with experts in the field. The statsR package is great and this is a great way to showcase its capabilities. This course is OK but I think the delivery could be improved upon.

Thanks

Provide bunches of intuition of bayesian statistics. Worthwhile to enroll!

Theorethical backdrop is a bit excessive on an R focused course

Very large drop in quality from the previous three courses in the specialization. Unlike the previous classes, there is not a quality textbook provided. What passes for a "textbook" is essentially a written re-hashing of the lectures which provides no new examples. The lectures themselves can be hard to follow and often times skip over important calculations. There are no practice problems. The labs are also less clear and there are major leaps between what is taught and what we are expected to know to solve the problems. The lack of quality resources and poor teaching coupled with the more challenging material made this course very frustrating.

The course has seen a lot of improvement with new study materials and videos. I'd say that this is now much better than what the course was previously.

I want to give 0 ratings. The worst course I have seen so far in Coursera. Horrible planning, horrible execution and makes no sense. Totally disappointed by the style of course design and delivery
