The paper estimates the covariance between liability to a disorder and age at onset in censored populations using a mixture distribution model applied to twin data.

This paper develops a covariance model to quantify mtDNA effects on human behavior using extended pedigrees and evaluates its statistical power and bias through simulations.

This paper applies a 3-level multilevel model to twin data, showing that regional clustering explains 1.8% of children's height variance, which is ancestry-related and disappears after genetic principal components correction.
