1 Objective

Here we will implement a Bayesian version of the classical T-test. We will also explore some ways to summarize the JAGS output, and we will introduce the concept of derived quantity.

2 The data

We will use the example from Marc Kery’s Introduction to WinBUGS for Ecologists, page 92 (Section 7.1 - t-test). The data describe wingspan of male and female Peregrine falcon (Falco peregrinus).
