Homoscedasticity

Hi' everyone,

I would like to perform a test (Levene or Bartlett) for testing the homogenity of variances before comparing two populations with a GLM procedure.

Previously, with the SAS software, I used :

proc anova;

class group;

model variables =group;

means group/hovtest=levene;

run;

but now Altair returns that "hovtest" is not supported at present for means statement..

Q: How can I test the homogenity of variances in ALTAIR ?

Thanks in advance for your kind answers.
