Dear all,

I have seen this post by Arthur Gilmour in an ASReml related forum:
> GLMM models have only been developed for the case of a single GLMM 
> trait. It is difficult to conceive what is the appropriate error 
> structure for bivariate GLMM traits when the variances are defined as

I would like to know what people on this list think about these issues 
e.g. if we want to estimate correlations between 2 traits with a poisson 
distribution, are there some special issues to take into account?

Thanks a lot in advance for your help,

All the best

Celine
