HollBivSym: Hollander Bivariate Symmetry

Description

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

Usage

HollBivSym(x,y=NA)

Value

Returns the observed Hollander A statistic.

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))

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)
