Version 8c

Two simple R functions to compute multivariate standardized differences between two groups (Mahalanobis’ D), either from raw data or from Cohen's d values and correlations. The functions return uncorrected and bias-corrected values of D, exact confidence intervals, bootstrapped confidence intervals (only from raw data), heterogeneity coefficients, and a number of additional diagnostics and effect sizes. Disattenuated estimates can also be computed if desired.
