Hi Alberto, I first need to evaluate my need. There is a number of statistical tools that I need, which at the end may be quicker to directly implement them than relying on an external library (which also comes with its own bag of issues by the way).

Hi Alexandre,
My question about a connection between Pharo and Python [1] is related to the issue you are reporting. In Python, they have numpy [2], which offers almost anything one would need for statistics, algebra, ... Instead of re-implementing everything in Pharo (aka re-inventing the wheel), imho, it would be much better to be able to exploit the good work already done by these smart people.
My interest to Alien FFI is also related: Instead of using numpy, one could use the external interface offered by MATLAB [3] (in the form of C APIs) to let it do the number crunching. Even though the MATLAB external interface is very simple and clean, I have not being able to use it from Pharo, yet, because I cannot make Alien work under Linux (where my MATLAB resides). I have also tried nativeboost, but I am still not able to create the VM with the necessary plugin to make it work. It is very frustrating: Even if I am working with Fernando (who knows Alien very good), in three days we have not reach any target.
It would be awesome if someone else wanted to give me a hand with this task: I believe It would be of interest for many of us.
Cheers, Alberto

Hi!
Is there a statistic library in Pharo? Computing the correlation, linear regression, ...
