Power and Sample Size Calculation for Logistic and Cox Models

This application calculates the power and sample size for the Cox and Logistic Models. It is written in Matlab/Octave. If you have Matlab (or it's free version, Octave) on your computer you can download the source files that are in the zip file "cox_and_logistic_matlab_programs.zip" . The programs to run the model are powl8 for the logistic model and powc9 for the cox model. The other programs are necessary helper functions which must be on your path. Included is a link to download Octave. If you don't wish to use the Octave/Matlab version you need to download and run the MCRInstaller first and then use the zip file "logistic_cox_power.zip".
