- I would like to do Bartlett's test for homoscedasticity (equality of
- variance) in SAS/STAT. It's useful for checking the equal-variance
- assumption of regression and ANOVA, and I was surprised that I
- couldn't find it in the manuals. It could be done semi-manually by
- outputting group variances from PROC MEANS and computing the test stat
- in a DATA step, but I would like to do it automatically.
-
- Does anyone know a SAS PROC that does this test? Thanks.
