混合模型中的层三角变换估计

ESTIMATION IN MIXED MODELS VIA LAYER TRIANGULAR TRANSFORMATION

提出了有着广泛应用的混合线性模型中参数估计的一种新方法，称为层三角变换估计。将该变换用于检验和估计中，将产生一整套用于全面分析混合线性模型的计算过程。这些过程在计算上是稳定的。

A new alternative for estimating parameters in some widely used mixed linear models is proposed. The approach is called as the layer trainglar transformation estimation. Using the same preliminary transformation for both testing and estimation gives us an integrated set of procedures for the full analysis of mixed linear models. The proposed procedures are computationally stable and space saving.
