Dear Martin,
thanks for correcting my previous A-lacking code.

Kind Regards,
Carlo

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
bootstrap r(Var), reps(50) : sum
--------------end example--------------

HTH and Kind Regards,
Carlo

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
