回顾性分析了新南威尔士州小麦品种试验的大型数据库。这项分析包括三个关键步骤。最初的误差方差异质性建模，由于试验地点，试验年，播种日期和试验平均产量的误差方差显着差异。讨论了该模型对方差分量估计的意义。
The retrospective analysis of a large database on wheat variety testing in New South Wales (NSW) is considered. This analysis involved three key steps. Initially error variance heterogeneity is modelled, indicating significant differences in error variance due to trial location, year of trialling, sowing date and trial mean yield. The implication of this modelling for the estimaion of variance components is discussed.
