Dear Hern��n,

 

I will put the code in my own repo with a configuration that you can import.

NumericalMethods package seems to contains the same things that Scismalltalk. So there is no timeseries methods.

 

Cheers,

Vincent

Dear Serge,

That's nice but I will need more statistical functions to calculate autocorrelations.

 

Have you checked NumericalMethods package? (is available from the Configuration Browser)

 

These functions are already implemented in R (http://www.r-project.org/).
So, there is two solutions:
- As the sources are open, implement them in Pharo (but it is some thousands of lines...)
- With nativeboost, use the R libs (written in C)

As I prefer the second solution, I began to write some code with native boost and it seems to work well.
I can add them in SciSmalltalk package if I have the rights. But I don't know how to package the R libraries for the different OS...

 

I would ask you if you can put this code into its own repository, so we can use the R binding without need to load the whole SciSmalltalk, and SciSmalltalk could import your Configuration.

Cheers,

Hern��n

Vincent Blondeau

We started a really simple implementation of time series. Look at the class : KETimeSeries and KETimeSeriesTest in this repository: http://smalltalkhub.com/#!/~UMMISCO/Kendrick

Please feel free to extract these classes and extend them. Maybe we can move them in the SciSmalltalk repository.
