BIGFAM - variance components analysis from relatives without genotype [PDF]
Nature CommunicationsEstimating variance components of phenotypes provides a fundamental basis for understanding complex traits. However, most existing methods require genotype data, which is costly to obtain and often unavailable, limiting their scalability. To address this

Estimators and tests for variance components in cross nested orthogonal designs
Discussiones Mathematicae Probability and Statistics, 2023 Explicit expressions of UMVUE for variance components are obtained for a class of models that include balanced cross nested random models. These estimators are used to derive tests for the nullity of variance components.

Leave-Out Estimation of Variance Components [PDF]
, 2018 We propose leave-out estimators of quadratic forms designed for the study of linear models with unrestricted heteroscedasticity. Applications include analysis of variance and tests of linear restrictions in models with many regressors.
