Wilcoxon Rank-Sum Statistic
Description
Compute the Wilcoxon rank-sum statistic.
Usage
rankSum(data, selector)
Arguments
data
numeric vector
selector
logical vector the same length as data
Details
This is an efficient function to compute the value of the Wilcoxon
rank-sum statistic without the extra overhead of the full
wilcox.test function. It is used internally by the
MultiWilcoxonTest class to perform row-by-row Wilcoxon
tests.
Value
Returns an integer, the rank-sum of the subset of the
data for which the selector is true.
