Maxima and Financial Applications



I am interested in using Maxima for financial
applications (portfolio investment and macroeconomics
studies).
I browsed through Maxima's manual, but the part about
statistics looked quite slim (only a Gaussian random
number generator was listed).
I would like to know if other packages are available.
I could eventually write some scripts myself, but I
would prefer some packages which has already been
extensively tested.
In particular, I am interested in the following:

1)linear regression and non-linear fitting (e.g.
Levenberg-Marquardt)
2)having a family of statistically relevant
distribution to study empirical data
3) numerical constrained optimization of function.

Best Regards
Lorenzo
