Vincent, can you tell a bit more what this binding is about? how can I try? Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Hi,
That's a very good idea. For now, I use a Pharo-R binding to make the statistics, but it is better if it is directly in the image.
For my part, it should be nice to have: - Principal Component Analysis - Time series - Correlation with several variables (Correlation matrix) + significance tests (pearson, spearman...) - Standard statistical tests: normality, variance, mean, distribution - And the more important is to have nice tools to visualize the data (Box plot, histogram, scatterplots, PCA ones) with a simple API for standard things but that we can customize. The best is that we are able to draw regression lines on them. But I think that is more a Roassal part.
Thanks for the initiative,
Cheers, Vincent
-----Message d'origine----- De : Pharo-users [mailto:pharo-users-bounces@lists.pharo.org] De la part de stepharo Envoyé : mercredi 2 mars 2016 14:17 à : Pharo Development List; Any question about pharo is welcome; Didier Besset; Souissi Sami Objet : [Pharo-users] Call about Numerical Methods in Pharo :)
Hi guys
I met Didier Besset and we had a great hacking session and discussions with Serge Stinckwich. Didier would like to help Pharo and the numerical part of it. ***Big thanks*** Didier.
We would like to do several things:
- Work on "Hows to" The numerical methods in Pharo is good but the gap between us and the math is too large :) so the idea is to have a series of "how to ..." - histomgram (simple, based on distribution)
- Improve the SciPharo/NumPha (previously SciSmalltalk) library This morning we started to implement a ComponentPrincipalDecomposition by combining two of the objects available in SciPharo. Then we started to enhance the distributions to make sure that we can plug other distribution for having controlled random number.
- Do a public call to know what is missing for you: this is this mail :) Didier would like to work on concrete cases. I love that attitude So tell us :)
Hernan ?? Alex: ?? pvalue? better distribution? Vincent: covariance? CPA? Philippe: times series Serge R frames? Sami: Better random number and various distributions?
- Organise a two day lectures with practices on concrete case in September with a recording session. Either at IRD Bondy or Lille.
- Make sure that the Numerical Method book will get on lulu :) with a better cover and title :)
