W_stat: Wilcoxon Sign Rank Test Statistic Exact Distribution

In wilcoxmed: Computes Values for the 1-Sample Wilcoxon Sign Rank Test for Medians

Description

This function allows the user to find the probability values from the exact distribution of W, Bickel and Doksum(1973). The exact P(W=x), P(W<=x), P(W>=x) values is found via an exhaustive enumeration of the possible permutations of data with size n.

Usage

W_stat(n , test_stat, side = c('geq','leq','eq'))

Arguments

n	Size of data or Number of observations
test_stat	The x value specified in P(W=x), P(W<=x), P(W>=x)
side	The tails of exact probability the user wants to compute e.g. 'eq' = P(W=x), 'leq' = P(W<=x), 'geq' = 'P(W>=x)

Value

The exact probability values as specified.

Examples

W_stat(n=5, test_stat = 3, side = 'leq')
