Statistics package in Pharo?
Hi everyone, Does anyone know if there is a package that contains implementation of statistics tests like Kolmogorov-Smirnov test, Khi-2 test, etc? I did fast research in Smalltalkhub but didn't found anything. Thanks in advance, Julien
The only package that I know that has statistical tools is NumericalMethods, you can install it by going to tools->Configuraiton Browser->NumericalMethods. Check if it has what you need 2015-03-03 11:40 GMT+01:00 Julien Delplanque <julien@tamere.eu>:

Wow lots of classes, I'll browse the package and tell you if that's what I need :) Thanks. On 03/03/15 11:46, Sebastian Tleye wrote:

Hi Julien, Indeed, having a nice statistical package is missing in Pharo. The numerical methods is a nice start. If things are missing, we should implement them. Cheers, Alexandre

Doesn't look like there is what I'm looking for. Maybe I'll implement things I need if I have time but probably not a complete package for statistics. :) On 03/03/15 12:46, Alexandre Bergel wrote:

Hi Julien, If you are doing some statistics, I am pretty sure that you use R. There is a connector to R software implemented in Pharo. You can use it if some methods are not implemented or too complex to do it by yourself. The link is here: http://www.smalltalkhub.com/#!/~VincentBlondeau/RProjectConnector/ Don't hesitate to ask if you need some help on it.

This is not really difficult to implement a khi2 or ks-test. I'm doing that with my 1st year university student in Python. I will try if I found sone time in Pharo. Sent from my iPhone

I know it's not complicated, I had to implement KS test in python for another project (but I don't think you are one of my professor :p).
I will do it soon but I'm still noob in smalltalk so I don't know where to implement this and how: class messages or object messages for example? Julien
I use class method for generic actions that are not to be performed per instance of data. But if I have multiple instances of data then instance methods make more sense. Some classes offer both instance and class methods doing the same process. So in the end its up to you there is no golden rule. For example you may have a class method that return the instance of the class which you can then use to trigger additional instance methods.

It does not really matter. Start to write your stat test and we will go over it. This is --highly-- important to have such tests. Alexandre

Hi Julien, there is no KS-tests in this package. This is also something I'm looking for :-) NumericalMethods package is now part of SciSmalltalk distribution: https://github.com/SergeStinckwich/SciSmalltalk Join us if you want to help build statistical tools in Pharo: http://groups.google.com/group/scismalltalk Regards Sent from my iPhone

Join us if you want to help build statistical tools in Pharo: http://groups.google.com/group/scismalltalk I'm interested since I have to implement things for a project, if it's possible to integrate them in your package it would be nice.
