CLTEST: Stata modules for performing cluster-adjusted chi-square and t-tests

Statistical Software Components from Boston College Department of Economics

Abstract: cltest is a pair of programs for analyzing data that have been randomized in clusters. clttest compares the means of two sets of grouped outcomes, with optional support for group-stratified outcomes. clchi2 estimates an adjusted chi-square test of independence for 2xk groups, with optional support for group-stratified outcomes. Adjustments for clustering are taken from Donner & Klar (Cluster Randomization Trials in Health Services Research, 2000), with the CLCHI2 program generalized to the 2xk case. chchi2 uses loneway to calculate the inter-cluster correlation, which in Stata 6.0 and higher includes a correction for imbalanced groups.
