This paper proposes an extension of the Mantel-Haenszel rate ratio for the dichotomous exposure to the multiple exposure levels. This extension is based on the unbiased estimating function approach and yields closed-form Mantel-Haenszel rate ratio estimators. Dually consistent variance and covariance estimators of the estimating functions are given and a quasi-score-based confidence interval for individual common rate ratio is provided. A similar extension to the common rate difference case is also given.
本文针对多暴露水平的二分类暴露情况，提出了曼特尔 - 亨塞尔率比的一种扩展。这种扩展基于无偏估计函数方法，并得出了封闭形式的曼特尔 - 亨塞尔率比估计量。给出了估计函数的双重一致方差和协方差估计量，并提供了基于拟得分的个体共同率比置信区间。还给出了共同率差情况的类似扩展。
