Carl,

There is a procedure in Rosner [Rosner, B. "Fundamentals of Biostatistics, (6th ed.), Duxbury, Press (The Thompson Company): Belmont, CA, 2006, pgs. 199-201.]

If you send me your email, I can pass along a "not-ready-for-prime-time" .ado that I use for the calculation.

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
