Make that

bootstrap r(Var), reps(50) : sum A

Otherwise, no result is returned (and no error, either...).

Dear Carl,
are you looking for something like the following example (flag: Stata
9.2/SE)?
--------------begin example--------------
set obs 10
g A=uniform()
sum A

Oggetto: st: Fw: Calculating a confidence interval for population variance
based upon sample.
Hi
I have STATA10.
I can not figure out how to calculate a simple confidence interval for a
population variance
based upon sample data. STATA will calculate the sample standard deviation,
but I can not figure out how to compute a confidence interval for the
population standard deviation. Is there a command which will do this?
Any help?
Thanx,
Carl
