Perfect - thanks.

I have a dataset of 1500 observations, each with an
identifier and a -y- value. -y- is highly skewed, and
nothing I've tried seems to normalize it.

I'd like to simulate the distribution of -y-. Is there
a reasonable way to do this if I can't find a transform
of it that looks like a standard distribution?
You can sample with replacement from the empirical distribution of y using -bsample-:

keep y
bsample
The variable y is now a random draw from the empirical distribution of y.

Hope this helps,
Maarten
