Type of Tool SAS Macro
Title Effect Size Mixed
Programmer/Email RuiChen
Contributing Site Rochester
Description This macro computes effect sizes for nested study designed data; it compares the group means between two treatment conditions with adjustment for clusters and fixed/random effect covariates and prints out effect size estimates for each of the endpoints if multiple outcome variables are included in the macro with same set of covariates.

Effect size is defined as Cohen's D for comparing two treatment groups --- difference between two group means divided by the pooled standard deviation --- with the group means and variance estimated from an analysis of covariance (ANCOVA) model.
