Genetic heteroscedastic models for ordinal traits: application to sheep litter size.

Genetics, selection, evolution : GSE - 1 Apr 2016

Fathallah Samira, Bodin Loys, David Ingrid

Abstract excerpt

BACKGROUND: Classical genetic canalization models, which accommodate the mean and variance of a trait separately, provide a flexible approach to take heteroscedasticity for continuous traits into account. However, this model is not appropriate for discrete traits. The aim of this work was to propose heteroscedastic threshold models suitable for the genetic analysis of ordinal data. METHODS: In order to first fit...
