Re: bivariate random regression

Dear Chevrotiere,

I've added the remained code lines,

Regards,

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)
1 2 2
0 0 0
2 0 US 0.1 0.01 0.1 !GP
leg(dim,1).Tr.anim  2
4 0 US !GP
1
0.1 1
0.1 0.1 1
0.1 0.1 0.1 1
anim 0 AINV
leg(age,1).Tr.ide(animam) 2
4 0 US !GP
1

0.1 1

0.1 0.1 1

0.1 0.1 0.1 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 ?

thanks
