In GRousselet/rogme: Robust Graphical Methods For Group Comparisons

Cliff's delta test

Description

Compute Cliff's analog of WMW test. Compute a confidence interval for delta using the method in Cliff, 1996, p. 140, eq 5.12. The null hypothesis is that for two independent group, P(X<Y)=P(X>Y). This function reports a 1-alpha confidence interval for P(X>Y)-P(X<Y).

Usage

cid(x, y, alpha = 0.05)

Arguments

x, y	Two vectors. Missing values are automatically removed.
alpha	Alpha significance level.

Details

cid returns a list containing the value of the test statistic, its confidence interval, and its p value.
