The parameter of a chi-squared distribution, used by Chisq-class
Objects from the Class
Objects can be created by calls of the form
new("ChisqParameter", ncp, df).
Usually an object of this class is not needed on its own, it is generated automatically when an object of the class Chisq
W=new("ChisqParameter",df=1,ncp=1) ncp(W) # ncp of this distribution is 1. ncp(W)=2 # ncp of this distribution is now 2.
