Your point is well taken. I think I will focus on the second part, as
there seems to be much more interest in the statistical functionality.
And my work would undoubtedly be better if focused.

I will have a closer look through Scikit learn and econpy and revise.

I agree. There has been some discussion of the most appropriate way
to handle this in your thread previously mentioned (eg., it would not
always be appropriate to force conversion to a masked array, should
stats and mstats be merged, etc.), and I would appreciate any
direction that could be offered. I like the idea of the "usemask"
flag here http://mail.scipy.org/pipermail/scipy-dev/2009-February/011414.html
but obviously would defer to others for the best solution. Should I
be spending most of my time looking through mstats rather than stats?

Very good idea.
Thanks for some initial feedback. I will take under advisement and
revise my proposal as needed.
Best,
Skipper
