statist: Bug in KS-Liliefors Test

[Andreas Beyer]

Hi,

I have found a bug in the evaluation of the KS-Liliefors test of 
statist: Hypothesis 0 is rejected when the D-value is below the critical 
D-value. However, it should be the other way round: The hypothesis is 
accepted when the D-value is above the critical value.
The problem is located in the function 'pks()'. I have not yet written a 
patch, but I will do so as soon as possible.

Cheers,
	Andreas
