sorry to all:

I'm looking for a way to display the statistical links between 
categories of observations and active variables (or characteristic 
modalities).

SAPD call this "Description of Modalities" - procedure DEMOD which 
statistically characterises each category of the dependent variable 
with the categories of other variables. Finally the characteristic 
modalities are arranged in descending order of statistical 
significance.

Are there a package for this kind of analysis?

Thanks
