A generalized Defries-Fulker regression framework for the analysis of twin data.

Behavior genetics - 1 Jan 2013

Lazzeroni Laura C, Ray Amrita

Abstract excerpt

Twin studies compare the similarity between monozygotic twins to that between dizygotic twins in order to investigate the relative contributions of latent genetic and environmental factors influencing a phenotype. Statistical methods for twin data include likelihood estimation and Defries-Fulker regression. We propose a new generalization of the Defries-Fulker model that fully incorporates the effects of observed...
