I know we're planning to discuss at SciPy in Austin and will hopefully have a gameplan. We should coordinate the discussions / implementation somewhere. I've implemented some groupby functionality in pandas but I guess at a higher level than what's been proposed to add to NumPy. On the pystatsmodels mailing list we've been starting to have some discussions about statistically-oriented data structures in general-- I'll be sending an e-mail to the NumPy mailing list soon to start a broader discussion which will hopefully lead to some good things at the conferences. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
