Parent-offspring and sibling correlation estimation based on MINQUE theory. (English) Zbl 0778.62101

Biometrika 80, No. 2, 393-404 (1993).

Summary: We derive easily computable expressions for MINQUE estimators of covariance parameters in an unbalanced family data structure used to study traits. These estimators are strongly consistent and asymptotically normal. Simple expressions for limiting sample variances and covariances of MINQUE estimators are provided.
