列联表的对数线性模型具有拟合程度高,对期望频数的下限不提任何要求,计算特别简便的特点。本文介绍二维r×s列联表的一般形式及其对数线性模型,并利用2×s列联表的对数线性模型分析四种植物生长调节剂在荔枝雌花期处理对座果率的影响。
The logarithmic linear model of the contingency table has a high degree of fitting, and does not mention any requirement for the lower limit of the expected frequency, so the calculation is particularly simple and convenient. In this paper, we introduce the general form and logarithmic linear model of two-dimensional r × s contingency table, and use logarithm linear model of 2 × s contingency table to analyze the effects of four plant growth regulators on fruit set rate influences.
