Compute Effect Sizes

This package contains several functions for calculating and converting various statistics, such as a t-test or p-value and sample size, to effect size estimates of d (mean difference), g (unbiased estimate of d), r (correlation coefficient), z (Fisher's z), and log odds ratio. The variance of these estimates are also computed. These calculation/conversion functions are a particularly useful resource during the preliminary stages of a meta-analytic project when deriving effect sizes from reported data. This package uses recommended formulas as described in The Handbook of Research Synthesis and Meta-Analysis (Cooper, Hedges, & Valentine, 2009).
