clus.rank.sum: Cluster Rank Test

Description

This package consists of methods that compute rank based tests for clustered data.

Usage

clus.rank.sum(Cluster, X, grp = NULL, Y = NULL, test = c("DS", "DD", "SDS"))

Arguments

Cluster
Cluster ID
X
Outcome variable
grp
Binary group indicator variable (0 or 1) if test= "DS" or "DD"
Y
Matched outcome variable if test="SDS"
test
"DS" =Datta-Satten rank-sum test, "DD" = Dutta-Datta rank-sum test, "SDS" = Data-Satten signed rank test

Value

pvalue
P-value for the test
Test Statistic
Test statistic value for the test
