NSM3 (version 1.1)

pKW: Kruskal-Wallis

Description

Function to compute the P-value for the observed Kruskal-Wallis H statistic.

Usage

pKW(x,g=NA, method=NA, n.mc=10000)

Value

Returns a list with "NSM3Ch6p" class containing the following components:na vector containing the number of observations in each of the data groupsobs.statthe observed H statisticp.valupper tail P-value

Details

The data entry is intended to be flexible, so that the groups of data can be entered in either of two ways. For data a=1,2 and b=3,4,5 the following are equivalent: pKW(x=list(c(1,2),c(3,4,5))) pKW(x=c(1,2,3,4,5),g=c(1,1,2,2,2))
