heterogenous regression slopes in mancova


New Member
Hey guys,

I have a little problem with my MANCOVA data (4 DVs, 3 Covariates). For one of the covariates and one of the DVs, the assumption of homogeneity of regression slopes is violated.

Does this mean my overall MANCOVA results may be affected or does this just concern the single DV in question?

Should I dismiss the covariate or keep it in the analysis?

Thanks in advance for any advice! :)
