Coverage of Statistical Analyses |
The GLMPOWER procedure covers power analysis for Type III tests and contrasts of fixed effects in univariate linear models, optionally with covariates. The covariates can be continuous or categorical. Tests and contrasts involving random effects are not supported.
The POWER procedure covers power analysis for the following:
tests, equivalence tests, and confidence intervals for means
tests, equivalence tests, and confidence intervals for binomial proportions
multiple regression
tests of correlation and partial correlation
one-way analysis of variance
rank tests for comparing two survival curves
logistic regression with binary response
Wilcoxon Mann-Whitney rank-sum test
The Power and Sample Size application covers a large subset of the analyses in the GLMPOWER and POWER procedures.
