pHollBivSym: Hollander Bivariate Symmetry

Description

Function to compute the P-value for the observed Hollander A statistic.

Usage

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

Value

Returns a list with "NSM3Ch5p" class containing the following components:mnumber of observations in the first data group (X)nnumber of observations in the second data group (Y)obs.statthe observed A statisticp.valupper tail P-value

Details

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