Software in Maths for Economists
First Bayes is a teaching package for elementary Bayesian statistics. Distributions from any of thirteen standard families may be plotted and many summaries computed. The prior distribution, likelihood and posterior distribution can be plotted on a single "triplot". First Bayes is offered free to anyone interested in teaching or learning Bayesian Statistics, provided it is not used for profit. The author notes "First Bayes is really old! Realistically, there is no prospect of it being updated, but it still works and does what it was originally intended to do."
