The aim of the module is to introduce the basic notions of Bayesian statistics, showing how Bayes Theorem provides a natural way of combining prior information with experimental data to arrive at a posterior probability distribution over parameters and to show the differences between classical (sampling theory) statistics and Bayesian statistics.
At the end of the module you should be able:
- To understand the basic notions of Bayesian statistics;
- To prove and use Bayes Theorem in its various forms;
- To carry out an analysis of normally distributed data with a normal prior distribution;
- To be able to carry out a significance test of a point (or sharp) null hypothesis using a full Bayesian methodology;
- To understand the differences between classical statistics and Bayesian statistics.
- Introduction and binomial model
