This course teaches you how to use the POWER and GLMPOWER procedures to compute prospective power and sample size calculations.
- estimate the parameters for a power analysis
- conduct a sensitivity analysis of the parameters
- perform power analyses on a two-sample t-test, a multiple regression model, a one-way ANOVA model, a two-way ANOVA model with covariates, multiple logistic regression model, and the comparison of two survival curves.
