Bayesian estimation for two groups

This Python package implements the software described in

Kruschke, John. (2012) Bayesian estimation supersedes the t test. Journal of Experimental Psychology: General.

It implements Bayesian estimation for two groups, providing complete distributions for effect size, group means and their difference, standard deviations and their difference, and the normality of the data. See John Kruschke's website on BEST for more information.

Requirements

  • tested with Python 2.7 (not Python 3)
