The finite-sample properties of various point estimators of a common odds ratio from multiple 2 X 2 tables have been considered in a number of simulation studies. However, the conditional maximum likelihood estimator has received only limited attention. That omission is partially rectified here for cases of relatively small numbers of tables and moderate to large within-table sample sizes. The conditional maximum likelihood estimator is found to be superior to the unconditional maximum likelihood estimator, and equal or superior to the Mantel-Haenszel estimator in both bias and precision.
在一些模拟研究中，已经考虑了来自多个2×2表格的共同优势比的各种点估计量的有限样本性质。然而，条件最大似然估计量受到的关注有限。对于表格数量相对较少且表格内样本量为中等至大的情况，此处部分纠正了这一疏漏。研究发现，条件最大似然估计量优于无条件最大似然估计量，并且在偏差和精度方面等同于或优于Mantel-Haenszel估计量。
