I've tried running 'nnmatch' to do some bias-corrected matching
estimation, and it seems to be taking FOREVER (i.e. hours and hours with
no clear improvement). Does anyone have any experience with this command?
Is this standard, or does this imply that something is wrong?

It even seems to go on forever with a "sample" drastically reduced data

Thanks so much! I love the accumulated expertise on this list!
