Hi Alex, Here are some references: WJ Gauderman (2002), "Sample size requirements for matched case-control studies of gene-environment interaction", Stat Med 21:35-50. WJ Gauderman (2002), "Sample size requirements for association studies of gene-gene interaction", American Journal of Epidemiology, 155:478-484. WJ Gauderman (2003), "Candidate gene association studies for a quantitative trait, using parent-offspring trios", Genetic Epidemiology, 25:327-338. I think it works for quantitative trait. See the option 'continuous' in design. Pingzhao At 06:14 AM 1/30/2008, alex lam \(RI\) wrote: >Hi PingZhao, > >Are there any papers describing Quanto?
