4. Bayesian Statistics: From Concept to Data Analysis– Coursera

Rating- 4.6/5

Time to Complete- 12 hours

This is a Free to Audit course offered by the University of California, but this course is not for beginners. This course begins with the basics of probability and Bayes’ theorem. Then covers the concepts of statistical inference from both frequentist and Bayesian perspectives.

After that, you will learn methods for selecting prior distributions and building models for discrete data. And in the last, this course covers the conjugate and objective Bayesian analysis for continuous data.

You Should Enroll if-

  • You should have prior knowledge of basic statistics class (for example, probability, the Central Limit Theorem, confidence intervals, linear regression) and calculus (integration and differentiation).
