Abstract: hodgesl implements Hodges-Lehmann aligned rank test of the null hypothesis of no difference in an outcome variable between treated and control observations over matched or stratified sets. The test is an extension of the Wilcoxon signed rank test to matching with multiple controls. It may be employed in testing treatment effect that stratifies the sample on single or multiple covariates, where the number of strata compared to the number of total sample observations is large, and within a stratum each treated subject has more than one matched control. The test is needed when the analyst evaluates average treatment effect and performs a significance test of such effect after optimal matching.
