Dear all,

I would like to do a bivariate random regression model with a direct animal effect and an individual permanent effect.

My two traits are the weight and PCV (hematocrit). Both traits are measured at weaning until one year old on animals.

I have an idea for a univariate model on weight (tell me if I'm wrong !):
weight~mu leg(age,1).band*sex !r leg(age,1).anim leg(age,1).ide(animam)

But I have no idea how to write the model with the two traits and how to write the G matrix.

Anyone has done something similar ?
