Could you suggest a solution to a Profile analysis when the assumption of homogeneity of covariance is violated.
I have three groups with different number of observations in every group (197, 188, 167) and nine dependent variables.
When I run the test for homogeneity of covariances, I get a significant Chi-square statistic.
Thank you in advance.

thank you very much for your reply.
It was my assignment at the University, so I have just described the problems I faced while analysing the data (violation of heterogeneity of variances) and possible decisions.
However, I have not considered mixed modelling approach, just because I had no idea about that. But thank you for your suggestion, I am quite curious so I will try to apply it.
