Homogeneity of variance is the assumption that your data sets are equal in variance. It allows for the validation of ...

You can test this assumption in PROC GLM by using the HOVTEST option in the MEANS statement, requesting a homogeneity of variance test. This section discusses the computational details behind these ...

Levene's test of homogeneity is particularly appropriate for short run ... You can implement Levene's method by using the GLM procedure to construct a one-way analysis of variance for the absolute ...
