[SciPy-user] time series analysis
Tue Nov 6 14:17:07 CST 2007
Matt and I started TimeSeries each on our own, before merging our efforts last
Christmas. On my side, I was trying to find something equivalent to pyclimate
for my own purpose, but supporting numpy. I poked around this package a bit,
wasn't completely happy with it, then figured it would be as easy to redo on
top of numpy. It's while I was struggling with subclassing the masked arrays
of numpy.core.ma that I decided to reimplement maskedarray, which eventually
leads to the current version of timeseries.
If I'm not completely mistaken, numpy.core.ma is a translation via numeric of
Paul Dubois' s implementation for CDAT. So yeah, I could have followed that
path, but I was learning python at the same time and it was a very good
exercise to reinvent the wheel, thus adding more noise and confusion.
I do agree that there could be some linkage between timeseries, pyclimate and
CDAT, at least in terms of converting objects from package to another.
However, it's unlikely to happen any time soon. Nevertheless, I may try to
implement some of the functions of pyclimate and CDAT in numpy/scipy, when
I'll have the need for them.
What I would suggest you is to start with timeseries, as it's pretty easy to
use. Then, depending on what your needs are, you can start developing your
In any case, don't hesitate to contact Matt or myself if you need some
specific help. The TimeSeriesPackage page of the scipy wiki is a good start,
Matt did a terrific job.
