Abstract

This chapter provides methods for computing power with moderator models of effect size. The models discussed are analogues to one-way ANOVA models for effect sizes. Examples are provided for both fixed and random effects categorical moderator models. The power for meta-regression models requires knowledge of the values of the predictors for each study in the model, and is not provided here.
