A collection of statistical simulation and computation tools with a GTK GUI, to help teach statistical concepts and compute probabilities. Two domains are covered: I. Understanding (Central-Limit Theorem and the Normal Distribution, Distribution of a sample mean, Distribution of a sample variance, Probability calculator for common distributions), and II. Elementary Bayesian Statistics (bayesian inference on proportions, contingency tables, means and variances, with informative and noninformative priors).
A 'gWidgetsRGtk2' GUI for fitting and comparing GLM or GLMM (based on Douglas Bates' 'lme4' package). It is designed to make comparisons between numerous models easy, both numerically and graphically, which may be useful for teaching. Relevant plots are automatically produced for each model family. 'R2STATS' is *not* a generic graphical interface for R, but a GUI for statistical modelling in a model comparison approach.
