I’m a bit new to brms and bayesian modeling in general so this might be an obvious one. I am trying to calculate heritability (h2) of a single trait using a pedigree. In a simplified framework, I’m interested in what proportion of the variance of the trait of interest (phenotypic variance, VP) is c…

The phi in the output is the actual phi as you don’t predict it (but assume it to be constant across observations) and hence brms uses no link function (i.e., an identity link).
