Constrain Random Parameters in Multivariate Model

Post by SeamusHarvey » Mon May 13, 2019 7:39 am

Hello,

I am trying to constrain random parameters in a multivariate model to be equal and zero. The '1, -1' set-up works fine for me in a univariate model, but does not appear to be the case in the multivariate model. Would you be able to provide some advice on this please?

Thanks,
Séamus

This appears to be working for me for an example I just tested. Can you provide more details regarding the model that you are fitting, and the output you are getting? Have you checked whether it works with a model with fewer parameters?
