Hollander Bivariate Symmetry
Function to compute the Hollander A statistic for testing bivariate symmetry.
HollBivSym(x,y=NULL)
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. |
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))
Returns the observed Hollander A statistic.
