Bayesian Analysis for a Logistic Regression Model - MATLAB & Simulink Example

Bayesian inference is the process of analyzing statistical models with the incorporation of prior knowledge about the model or model parameters. The root of such inference is Bayes' theorem: In this formula mu and tau, sometimes known as hyperparameters, are also known. The following graph shows the prior, likelihood, and posterior for theta. In some simple problems such as the previous normal mean inference example, it is easy to figure out the posterior distribution in a closed form. But in general problems that involve non-conjugate priors, the posterior distributions are difficult or impossible to compute analytically.
