I am really interested in implementing ARIMA so I can try to help here where possible.

Hi @josepablocam & @sryza I am actually looking at the non-seasonal one, similarly to Madlib ARIMA implementation (I.e. To forecast Timeseries values): http://doc.madlib.net/master/group__grp__arima.html

Hi @josepablocam, no worries, looking forward to looking at your sketch and see where and how I can help. We can maybe focus on each of the sections of ARIMA,...

Actually there is already an AR module in the current package, maybe one should focus on the Differencing section and the other on the MA then.

@josepablocam apologies for the delay, I will be looking at this over the weekend as I have been quite busy at work. Thanks for sharing!

Not sure if you had the chance but I have been looking at how ARIMA got implemented in Madlib: https://github.com/madlib/madlib https://github.com/madlib/madlib/blob/master/src/modules/tsa/arima.cpp It's c++ but the mathematical approach is there anyway.
