Genetic Power Calculator (Sean Purcell and P C Sham)http://www.bristol.ac.uk/cmm/research/ebooks/
Stat-JR v1.0.5 is the first release of Stat-JR to include a suite of statistical analysis assistants (SAAs). The scope of the SAAs ranges from modelling a simple linear regression through to a combined SAA that will cope with: different response types (normal, binomial, Poisson and negative-binomial); multiple levels/classifications at which random effects can occur in both a nested or crossed way; random intercepts and slopes and interaction terms. Many of the SAAs use MLwiN (both IGLS and MCMC estimation) as the engine underneath the electronic book thereby joining up Stat-JR and MLwiN software packages that we distribute together. This software is free to academics.https://www.bristol.ac.uk/cmm/learning/online-course/
