Thanks for the hint! I can now calculate normal distribution and
chiĀ²-distribution. Do you know where I can find documentation on how to
calculate the ciritcal values (i.e. inverse) of students' (t)
distribution, F-distribution and for some non-parametric tests
(Newman-Keuls-test, Cochran-Test, U-Test, ...)
Thanks
Hansi
