I'm adding covariates to the means of a model.
The value of each covariate is read from the data as a definition variable ( "data.cov1", "data.cov2" etc) in a matrix named "defCovs"
As the betas are all in one matrix, I'd like to also have an "intercept" column, fixed at 1 in the the defCovs matrix to simplify the arithmetic.
Question: Is it legal to include fixed values along with definition variables in an mxMatrix?
so:
$labels "intercept" "data.age" $values 1 0 $free: FALSE FALSE
