How to determine the minimum sample size for simple logistic regression with a binary covariate. We now show how to estimate the statistical power and minimum sample size required for logistic regression. So the dependent variable is binary in nature and i decided to use logistic regression.

I have seven independent variables (three continuous and .

So the dependent variable is binary in nature and i decided to use logistic regression. This program computes power, sample size, or minimum detectable odds ratio (or) for logistic regression with a single binary covariate or two covariates and . The calculation is made using the free software . A later section presents the comparisons of these formulae with computer power simulations.
