Power analysis for logistic regression.
Designing an effective study requires balancing power, sample size, and cost. Stata's new power logistic command helps you determine the optimal sample size for logistic regression models without wasting time or resources.
Stata's power logistic command computes sample size, power, or effect size for the test of one coefficient of interest in a logistic regression model. As with all other power methods, power logistic allows you to specify multiple values of parameters and automatically produce tabular and graphical results.
