st: Fw: Calculating a confidence interval for population variance based upon sample.

["Carl Mastropaolo" <accuscience@comcast.net>]

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
