运用混合线性模型的分析原理 ,对 1 996年和 1 997年的四川省油菜区域试验的产量结果 (非平衡数据 )进行统计分析。结果表明 ,影响油菜产量的随机效应方差分量中 ,年份—试点互作方差分量最大 ,表明 9个试点的产量表现在1 996年和 1 997年很不一致。多重比较分析表明 ,绵阳 92 -4 592和 94 0 7N比对照中油 82 1增产达极显著水平 ,这与线性对比分析结果相似。据回归参数和置信区间判断 94杂 -4稳定性较好
Using the analytical principle of the mixed linear model, statistical analysis was made on the yield results (non-equilibrium data) of the regional rapeseed trials in Sichuan Province in 1996 and 1997 respectively. The results show that among the variance components of random effects that affect the yield of rapeseed, the largest component of the variance of the year-pilot interaction is the largest, indicating that the yields of the nine pilot projects are very different from 1996 to 1997. Multiple comparative analysis showed that the yield of Mianyang 92 -4 592 and 94 0 7N was significantly higher than that of the control Zhongyou 82 1, which was similar to that of linear comparative analysis. According to regression parameters and confidence intervals to determine the 94 hybrid -4 stability is better
