给出了在混合线性模型中构造一个性状遗传力的置信度区间的一系列步骤。该过程适用于为具有两个变化源的混合线性模型中的方差分量之比构造置信度区间。根据预期长度对结果间隔进行评估。调查者可以基于具有较短预期长度的区间(S)从程序族中选择最佳可信区间程序。使用来自红安格斯种牛群的公牛的眼球数据的可信区间将被提供。
A family of procedures is given to construct confidence intervals for the heritability of a trait in a mixed linear model. The procedures are applicable for constructing confidence intervals for a ratio of variance components in a mixed linear model having two sources of variation. The resulting intervals are evaluated in terms of expected length. The investigator may select the best confidence interval procedure from the family of procedures based on the interval( s) having short expected length. Confidence intervals for loineye data using bulls from a Red Angus seed stock herd will be presented.
