Levene's Test Reference

[The Burl]

Hello,

I have some significant Levene's tests for my MANCOVAs and am looking for justification to still move forward despite these results.

I heard somewhere that if the covariances for my variables are within three times each other it is OK to trust the ANOVA results. Also looking at the SDs seems to be an alternative too.

Does anyone have a reference for this covariance convention I heard about? Or, any other good references/tips for evaluating homogeneity beyond Levene's?

Thanks!
Jon
