Python statistics package: difference between statsmodel and scipy.stats
I think THE statistics package is numpy/scipy. It works also great if you want to plot your data using matplotlib. 
However, as far as I know, matplotlib doesn't work with Python 3.x yet.
I need some advice on selecting statistics package for Python, I've done quite some search, but not sure if I get everything right, specifically on the differences between statsmodels and scipy.stats.
One thing that I know is those with scikits namespace are specific "branches" of scipy, and what used to be scikits.statsmodels is now called statsmodels. On the other hand there is also scipy.stats. What are the differences between the two, and which one is the statistics package for Python?
Thanks.

I changed the title because some answers are not really related to the question, and I suppose that's because the title is not clear enough.
