HollBivSym: Hollander Bivariate Symmetry

In NSM3: Functions and Datasets to Accompany Hollander, Wolfe, and Chicken - Nonparametric Statistical Methods, Third Edition

Hollander Bivariate Symmetry

Description

Function to compute the Hollander A statistic for testing bivariate symmetry.

Usage

HollBivSym(x,y=NULL)

Arguments

x	Either a matrix containing both groups of data or a vector containing the first group of data.
y	If x is a vector, y is a required vector containing the second group of data. Otherwise, not used.

Details

The data entry is intended to be flexible, so that the data can be entered in either of two ways. The following are equivalent:

HollBivSym(x=matrix(c(1,2,3,4,5,6),ncol=2,byrow=T)) HollBivSym(x=c(1,3,5),y=c(2,4,6))

Value

Returns the observed Hollander A statistic.

Examples

##Hollander-Wolfe-Chicken Table 3.16 example
recipient<-c(61.4,63.3,63.7,80,77.3,84,105)
donor<-c(70.8,89.2,65.8,67.1,87.3,85.1,88.1)

HollBivSym(recipient,donor)

##Or, equivalently
table3.16<-matrix(c(61.4,63.3,63.7,80,77.3,84,105,70.8,89.2,65.8,67.1,87.3,85.1,88.1),ncol=2)
HollBivSym(table3.16)
