Levene's test of homogeneity of variances in ANCOVA
Posted: Tue Feb 25, 2020 10:13 am
Hello,
I was doing a univariate ANCOVA with the pre-test results as the covariate and the post-test results as the DV.
I ran the Levene's test of homogeneity of variance and somehow to my surprise, the test did not take the covariate into account - the results were just identical to running an ANOVA with no covariates specified in the model.
Has anyone else figured out similar problems and would the development team consider solving this in the next release?
Thank you very much!
