Re: st: RE: -collapse- versus homebrew
I'll accept the guess. But note that my example was only twice as
fast, so there would still seem to be some point where the more
efficient coding of -collapse- wins.

When we generate bootstrapped standard errors and perform Monte Carlo
analyses, it's useful to make the code as speedy as possible. So I
thought about -collapse- for a moment and performed the following
speed test listed below. The timing results follow it, showing that
my homebrewed version was twice as fast as -collapse-.
