compute.es - Compute Effect Sizes
Several functions are available for calculating the most
widely used effect sizes (ES), along with their variances,
confidence intervals and p-values. The output includes ES's of
d (mean difference), g (unbiased estimate of d), r (correlation
coefficient), z' (Fisher's z), and OR (odds ratio and log odds
ratio). In addition, NNT (number needed to treat), U3, CLES
(Common Language Effect Size) and Cliff's Delta are computed.
This package uses recommended formulas as described in The
Handbook of Research Synthesis and Meta-Analysis (Cooper,
Hedges, & Valentine, 2009). A free web application is available
at <https://acdelre.github.io/apps/compute_es/>.
