POWER V3.0 Software

POWER is a windows-based program for computation of sample size and power for binary outcome studies (case-control and cohort studies) based on a logistic-like regression model with one covariate or two covariates (e.g., gene X exposure interactions).

Download Software:

  • Download: Install_PowerV3.exe
  • Save this file in an appropriate folder on your disk.

the install program must be run from an account with installation privileges (ie. Power User or Administrator).

If you are not sure what privileges you have, please contact your System Administrator.
