chi square and mahalanobis
...the first point of each measure must be
1. To be clear I did:
x1<-x[,1:169]/x[,1]
where x and x1 are the unscaled and scaled sata sets, respectively.
However, after doing this (and eliminating the first point of each
measure), the points in the new QQ plot -
qqplot(qchisq(ppoints(382),168),XMahaNew) -
were still aligned, although they were no more along the y=x line.
Am I doing something statistically wrong ?
Thank you all in advance.
