('binary' encoding is not supported, stored as-is) If you are using a univariate model you can still define variance
structures for residuals and any other random factor (using structure
IDEN for an identity matrix) and then fix whatever you want using !GF
while letting the other components float using !GP.

Dear All,
I am wondering if it is possible to fix variance estimates in univariate
models, to be able to check the likelihood (given the estimates). In
multivariate cases one could use !F in the lines for specifying the
variance structure. I thought of specifying BLUP 2, and specify the
starting value behind the starting value in the model. But what if I
only want to fix one component and not all of them?

Thanks in advance
