[R-sig-ME] animal model: calculating heritability and evolvability from sire effects

[Szymek Drobniak]

Hi,

both your code and the way you calculate VA using sire variance seems
fine. In lmer residual variance is fixed as it assumes fixed
relationship between variance and mean in binomial data so I'm not
sure if simply putting this variance in your formula solves the
problem. In MCMCglmm residual variance quantifies overdispersion so as
far as I know here it's just a matter of substituting gaussian to
multinomial2.

Cheers,
sz.
