A common question of interest to researchers in psychology is the equivalence of two or more groups. Failure to reject the null hypothesis of traditional hypothesis tests such as the ANOVA F‐test (i.e., H0: μ1 = … = μ k ) ...
Specialized Tests for Detecting Treatment Effects in the Two-Sample Problem
(Taylor & Francis, 1997)
Nonparametric and robust statistics (those using trimmed means and Winsorized variances) were compared for their ability to detect treatment effects in the 2-sample case. In particular, 2 specialized tests, tests designed ...
Robust normative comparison tests for evaluating clinical significance
