The Minimum Norm Quadratic Unbiased Invariant Estimator of the estimable linear function of the unknown variance-covariance component parameter θ in the linear model with given linear restrictions of the type Rθ = c is derived in two special structures: replicated and growth-curve model.

Quadratic estimations in mixed linear models

Štefan Varga (1991)

Applications of Mathematics

Similarity:

In the paper four types of estimations of the linear function of the variance components are presented for the mixed linear model $𝐘 = 𝐗 β + 𝐞$ with expectation $E (𝐘) = 𝐗 β$ and covariance matrix $D (𝐘) = 0_{1} 𝐕_{1} + . . . + 0_{𝐦} 𝐕_{𝐦}$ .
