Versatile sample size calculation
About SimSam SimSam is a sample size calculation software add-on that can calculate the sample size needed to achieve given statistical power for any analysis, under any statistical model, that can be programmed in the host package. SimSam is free, and is currently available as an add-on for Stata (watch this space for details of future implementations in other packages such as R).

SimSam is designed to provide an accurate, transparent solution to sample size calculation which is straightforward for other statisticians (e.g. reviewers or members of funding panels) to validate. It can cope with non-parametric tests, multi-level models, multiple testing, group sequential methods, adaptive trial designs, and more.

SimSam was developed by Richard Hooper at Queen Mary, University of London.
