Greetings,
For a methodological framework I am developing, I need to test the difference between variances of two variables from the same population. The closest procedure I can find in Stata is sdtest (https://www.stata.com/manuals/rsdtest.pdf), which is described as a variance comparison test but actually tests the difference between standard deviations rather than variances. Without boring you with the details about why I need to test variances rather than standard deviations, can anyone point me to a procedure in Stata that will do the job?
Thanks,
Jeff Edwards
