Explanation

Here, we're performing a Bayesian update to estimate the risk of a patient getting infected by MRSA in a hospital. We start with a prior distribution that represents our initial belief about the infection rate. This prior is updated based on the observed data (number of infections and bed-days) using Bayes' theorem. The result is a posterior distribution which represents our updated belief about the infection rate.
