Dear S-People,
does anyone have some S-Plus-functions of test statistics which could
be used, when the assumption of normal distribution is invalid and a
test of identical variances shall be performed. Unfortunately our
distributions observed are well skewed to the right. Thus we are
searching for tests for dispersion in the two-sample case such like
the Siegel-Tukey, Mood, Ansary-Bradley, Moses or similar ones.
Can anyone help?
Susanne
