Abstract excerpt
The GEBV for health traits are typically published as probabilities obtained using threshold models. While these models benefit from theoretical properties, they require substantial computational resources and may face convergence issues. Linear models can be a good alternative, but solutions need to be approximated to the liability scale before converting the GEBV into probabilities. Recently, an approximation...
