What statistical functions are provided ?
All the usual descriptive statistics (bar charts, histograms, best-fit distributions on sample cdfs, dendrograms, box and whisker or cluster plots), multivariate statistics (distance matrices and dendrograms, principal components and scree plots), time series (ACF, PACF, ARIMA) and frequently used tests (mostly with exact p values not the normal approximations), such as: • chi-square (O/E vectors, m by n contingency tables and wssq/ndof) • McNemar test on n by n frequency tables • Cochran Q test • Fisher exact (2 by 2 contingency table) with all p values • Fisher exact Poisson distribution test • t (both equal and unequal variances, paired and unpaired) • variance ratio • F for model validation • Bartlett and Levene tests for homogeneity of variance • 1,2,3-way Anova (with automatic variance stabilizing transformations and nonparametric equivalents) • Tukey post-ANOVA Q test • Factorial ANOVA with marginal plots • Repeated measures ANOVA with Helmert matrix of orthonormal contrasts, Ma
