Power calculation for multiple comparisons of two independent samples on p variables using PROC IML in SAS.
Three SAS programs for determining power calculations for the Bonferroni-Holm and Hochberg multiple comparisons of two independent samples on p variables are described. Input to the three programs includes sample size to be considered, the alpha level, the number of replications for the simulations...

| Sumario: | Three SAS programs for determining power calculations for the Bonferroni-Holm and Hochberg multiple comparisons of two independent samples on p variables are described. Input to the three programs includes sample size to be considered, the alpha level, the number of replications for the simulations, and information about effect sizes and covariance matrix. Each program then calculates any-variable power, all-variable power, individual power, and average per-variable power for each procedure. An illustration of the programs' use and details regarding its availability are provided. |
