|Subject: ||Variance test for dependent groups with SAS|
Does anybody know a significance test concerning the variances of more
than two d e p e n d e n t groups? I am simulating ARIMA models, and I
expect the parameter estimations to get a larger variance under certain
conditions. I want to have a test to determine whether the differences
are systematic. And I also would like to calculate the s a m p l e
s i z e of my simulation. Cohen 1977 unfortunately has only tables for
some more used statistical tests.
Is there a SAS macro for this test?
Thanks in advance
