Dear List. I have logistic regression analysis with 10 binary predictors.  I tried to use NCSS PASS to determine the sample size for different effect sizes (OR = 1.5, 2.0, and 2.5), but the program only seems to use one predictor.  Does anyone know of any software that would allow one to determine sample size for a logistic analysis with 10 predictors?  Thanks,
