NLMIXED_Gaussian Quadrature Method

Dear all

I am working with SAS NLMIXED to run a bivariate-GLMM using two correlated random-effects to join the two responses together.


I’ve chose the Gaussian-Hermite (G-H) method for approximating the likelihood. I know the G-H formula for the univariate case but I couldn’t find a proper formula for the bivariate model, when I have two responses together.

I want to know which “G-H formula” SAS NLMIXED is using to approximate the likelihood function for bivariate regression models.


I appreciate your responses.
