Multivariate and Univariate Measures for Testing Homoscedasticity Across Groups: Example X5 moderated by X3

Created: Apr 16, 2021 08:49 AM  |  Last Modified: Jun 8, 2023 5:32 PM (1718 views)

I am trying to figure out how JMP can provide Multivariate tests for homoscedasticity, and univariate tests for homoscedasticity. 

So i have moderation of distribution x5 by a firm size x3 and my dependent variables are X19, X20, X21.

 

JMP does not provide for Box's m test but i can use Barlett. However, using to use both X5 and X3 ni the fit group cannot be done to get to these values for univariate. But i can also get Levene tests here. Can fit group test for Multivariate and univariate for homoscedasticity across groups X5 by X3?
