The large-sample relative efficiency of the Mantel-Haenszel estimator psi MH of an odds ratio is investigated for the case in which the number of strata is fixed and the sample sizes within each stratum increase indefinitely. The results show that psi MH is very efficient over a wide range of designs likely to occur in practice. However, conditions are identified under which the relative efficiency of this widely used estimator can be unusually low.
在层数固定且各层内样本量无限增加的情况下，研究了比值比的Mantel-Haenszel估计量ψMH的大样本相对效率。结果表明，ψMH在实际中可能出现的广泛设计范围内非常有效。然而，已确定了一些条件，在这些条件下，这种广泛使用的估计量的相对效率可能会异常低。
