Acerca de este Curso

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 really loved the previous courses because their reading material which was very good complimented by the video lectures, nevertheless, in this course, many of the video lectures was the repetition of the main book.

The pacing for this course was way faster than the previous ones, I think it would help if the course's length was twice as long covering each topic more slowly and having more videos.

Overall I think there are better options available for learning bayesian statistics. The pacing and structure of the course both felt off to me, spending too much time on some things (conjugacy in particular) and breezing past many other things too quickly (particularly numerical methods). I also thought that it would have been more helpful to learn to perform many of the analyses from scratch so that they could be better understood, rather than relying so heavily on the accompanying statsR package.

Clearly, Professor Clyde doesn't know how to teach.

Too many formulas... More examples would be nice.

Find it hard to follow the lectures. The labs and supplement material is good though.

Worst course in the specialization. Totally killed my interest in statistics and R. Warning to everyone, do not do this course if you have / want to learn statistics. Only do it if you want to re-enforce the view that statistics is not something for you.

Though this section in the specialization is a little more difficult than the other sections. The supplemental material provided is helpful in navigating through the course. I will continue to read through this material to further my understanding of the material.

Good for reviewing Bayesian Statistic. But not for new learners.

The quality is below the previous courses in the same Specialization. The contents are rushed. The labs are impractical and sometimes confusing.

And beware of the final assignment. Since the number of students is low, the grading takes lots of days. And you might miss the enrollment window for the Capstone course.

While the other modules so far have been terrific with good levels of support and clear explanations, this module is pretty terrible for a few reasons.

1) The level of support.

Your chances of getting a response to any question are slim - which means you're pretty much on your own here. Don't understand anything? Go find the answer elsewhere.

2) The tutors.

Mine Çetinkaya-Rundel has generally been terrific so far. Speaks slowly, repeats what variours terms mean (instead of assuming we memorize them the moment we hear them) and provides good clear examples to work from.

Sadly both Merlise and David are the opposite. They whiz through the material uncomfortably reading from a telepromter often assuming we instantly grasp every possible concept. It's almost impossible to follow most of the sessions they present. Most of the time there aren't even any exercises or opportunities to check we've understood the material correctly. They would both be 100% better if they frequently reminded us of the definitions of the concepts they use.

3) The material. There is FAR too much here to be covered in a single module. This is an entire course on its own (or a much bigger module).

4) Assumptions we know things which are never taught. I've lost track the number of times a word or concept sneaks into a quiz, into a lecture, or into an R package without explaining what it means. At times it feels this material was pulled from 2 or more sources and this has created gaps in understanding.

Sorry guys, I've really enjoyed the first three modules...but this one was a bit of a disaster.

Provide better support, shrink the material, create a better lecture experience and I'll happily revise this.
