GEmis: Power Calculations for Gene-Environment Tests Incorporating Misclassified Exposures
- SAS Macro (courtesy of Sara Lindstrom). [New (3 March 2009)!]
- Complete table of power calculations summarized in Lindstrom et al. (2009).
- Reference: Lindstrom S, Spiegelman D, Kraft P Hum Hered (in press).
PowerGxE: Power Calculations for Genetic Association Tests Exploiting Gene-environment Interaction
- SAS Macro (courtesy of Yu-Chun Jean Yen).

GECOR: Power for Gene-Environment Interaction Tests in Matched Case-Control Association Studies, Allowing for Correlated Environmental Exposures
- R functions, GUI front end, examples and manual (courtesy of Amy Murphy).
- Reference: Murphy and Kraft, submitted to Genetic Epidemiology.
MULTIPOW 2.1: Power for Multi-stage Genome-wide Association Studies
- R functions, examples and manual.
- Old version (replication-based power only).
- These functions are useful for designs with more than two stages. For two stages, I recommend the much more user-friendly CATS or the method described in Wang et al. (2006) Genet Epidemiol 30:356.
