相关有序数据的随机效应逻辑斯谛回归模型模拟与应用

Modelling correlated ordinal data by random-effects logistic regression models: simulation and application

Ali Reza Fotouhi, Theresa Mulder

摘要:

有序分类数据经常出现在生物医学、农业和社会科学数据的分析中。逻辑斯谛回归模型在分析有序分类数据时很有吸引力,因为它可以用来解释参数估计。有序响应可以被聚类,并且聚类内的受试者可以是正相关的。为了适应这种相关性,我们向每个聚类响应的线性预测因子添加一个随机分量。本文介绍并比较了用于分析有序分类数据的随机效应逻辑斯谛回归模型。所提出的模型应用于农业试验数据。为了评估随机效应和均质模型的性能,我们进行了模拟研究。我们的分析,应用到实际数据和模拟,表明个别类别的概率估计较差的同质模型。随机效应模型拟合具有统计学显著性的数据,并更精确地估计各个类别的概率。

英文摘要:

Ordered categorical data frequently arise in the analysis of biomedical, agricultural, and social sciences data. The logistic regression model is attractive in analyzing ordered categorical data because of its use in interpretation of a parameter estimate. The ordered responses may be clustered and the subjects within the clusters may be positively correlated. To accommodate this correlation we add a random component to the linear predictor of each clustered response. This article presents and compares random-effects logistic regression models for analyzing ordered categorical data. The proposed models are applied to an agricultural experimental data. In order to assess the performance of the random-effects and homogeneous models we perform a simulation study. Our analysis, application to real data and simulation, show that the probability of the individual categories are estimated poorly in homogeneous models. The random-effects models fit the data statistically significant and estimate the probability of the individual categories more precisely.
