PGA (Power for Genetic Association Analyses)is a package of algorithms and graphical user interfaces developed in Matlab for power and sample size calculation under various genetic models and statistical constraints. The software is designed to facilitate decision making for case-control association studies of candidate genes, fine-mapping studies, and whole-genome scans.
