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
