Likelihood ratio tests in behavioral genetics: problems and solutions.

Behavior genetics - 1 Mar 2006

Abstract excerpt

The likelihood ratio test of nested models for family data plays an important role in the assessment of genetic and environmental influences on the variation in traits. The test is routinely based on the assumption that the test statistic follows a chi-square distribution under the null, with the number of restricted parameters as degrees of freedom. However, tests of variance components constrained to be...
