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.
