27 May 2020 TI Methods Speaker Series: Power analysis in meta-analysis
It is a common bromide that a meta-analysis is more statistically powerful than any one constituent study. In reality, however, the situation is far more complicated. In this talk, I briefly review the concept of statistical power and the many factors that influence it. I discuss the basics of power analysis for the standard meta-analysis models, comparing and contrasting the implications when assuming fixed or random effects. I also discuss how heterogeneous power across constituent studies can complicate a resulting meta-analysis, and suggest ways to better account for such heterogeneity.
