Mixed model analyses via restricted maximum likelihood, fitting the so-called animal model, have become standard methodology for the estimation of genetic variances. Models involving multiple genetic ...

There are two ways to avert the negative effects of heterogeneity on parametric methods. One is to use maximum parsimony, which is not affected by heterotachy because it does not assume an identically ...

This example calculates confidence intervals based on the profile likelihood for the parameters estimated in the previous example. The following introduction on profile-likelihood methods is based on ...
