Marco,
You could try R, a totally free implementation of the S statistics
programming language:
R has everything you need. The main possible disadvantage of R (or S)
versus packages like SPSS/SAS is that they are much more programming
languages customized for statisticians rather than statistics
packages. So, they require more technical competence on the part of
users.
Chris.
