Basics of Bayesian Data Analysis Using R is part one of the Bayesian Data Analysis in R professional certificate.
Bayesian approach is becoming increasingly popular in all fields of data analysis, including but not limited to epidemiology, ecology, economics, and political sciences. It also plays an increasingly important role in data mining and deep learning. Let this course be your first step into Bayesian statistics.
Here, you will find a practical introduction to applied Bayesian data analysis with the emphasis on formulating and answering real life questions. You will learn how to combine the data generating mechanism, likelihood, with prior distribution using Bayes’ Theorem to produce the posterior distribution. You will investigate the underlying theory and fundamental concepts by way of simple and clear practical examples, including a case of linear regression.
You will be introduced to the Gibbs sampler – the simplest version of the powerful Markov Chain Monte Carlo (MCMC) algorithm. And you will see how the popular R-software can be used in this context, and encounter some Bayesian R packages .
A facility in basic algebra and calculus as well as programming in R is recommended.

If you have never used R before, it is also recommended to go through the chapters 1-7, and 9 of the R-manual found at https://cran.r-project.org/doc/manuals/r-release/R-intro.html
• Bayes’ Theorem. Differences between classical (frequentist) and Bayesian inference.
• Posterior inference: summarizing posterior distributions, credible intervals, posterior probabilities, posterior predictive distributions and data visualisation.
• Gamma-poisson, beta-binomial and normal conjugate models for data analysis.
• Bayesian regression analysis and analysis of variance (ANOVA).
• Use of simulations for posterior inference. Simple applications of Markov chain-Monte Carlo (MCMC) methods and their implementation in R.
• Bayesian cluster analysis.
• Model diagnostics and comparison.
• Ensuring you answer the actual research question rather than “apply methods to the data”
