It's okay. That stuff will just slip away if you don't use it on a regular basis. (I need to review some statistics myself.)

I'd be glad to consult on the problem, if that might help.

Thanks -I'm going to try to foist it off on the newly minted MBA in the cubicle next to mine, first, but if I end up desperate, I'll circle back to you.

(This in theory should not be anything terribly complicated. It's just that I'm realizing I only have the haziest memory of what R-squared means, which is pretty pathetic.)
