Variance components estimated by MINQUE method can be used in significance test for linear contrasts of variety effects.
用MINQUE法估算各项方差分量，然后对品种效应的线性对比作显著性测验。
For the litter size, variance components of maternal gametic effects were about twice than that of paternal gametic effects.
而在产羔数上，母系印迹效应方差大约是父系印迹效应方差的两倍。
The unknown parameters of this model are divided into two categories: one is the fixed effects, and the other is the variance components.
这种模型的未知参数分两类，一类是固定效应，一类是方差分量。
