On the likelihood ratio tests in bivariate ACDE models.

Psychometrika - 1 Jul 2013

Wu Hao, Neale Michael C

Abstract excerpt

The ACE and ADE models have been heavily exploited in twin studies to identify the genetic and environmental components in phenotypes. However, the validity of the likelihood ratio test (LRT) of the existence of a variance component, a key step in the use of such models, has been doubted because the true values of the parameters lie on the boundary of the parameter space of the alternative model for such tests,...
