各种渐近检验程序已开发，以前的检验相等的两个二项比例与部分不完全配对数据。丢弃不完全观察结果的测试过程已被证明不如利用所有可用观察结果的测试过程强大。另一方面，利用所有可用观测值的渐近检验过程在小样本问题或稀疏数据结构中可能不可靠。本文提出了在随机机制下，用部分不完全成对数据检验两个成对二项比例等式的无条件精确检验方法。所提出的无条件精确测试方法用神经学研究的真实数据加以说明。实证研究是为了调查这些和其他测试程序在尺寸和功率方面的性能。
Various asymptotic test procedures have been developed previously for testing the equality of two binomial proportions with partially incomplete paired data. Test procedures that discard incomplete observations have been shown to be less powerful than those procedures that utilize all available observations. On the other hand, asymptotic test procedures that utilize all available observations may not be reliable in small-sample problems or sparse data structures. In this article, unconditional exact test procedures are proposed for testing the equality of two paired binomial proportions with partially incomplete paired data under a random mechanism. The proposed unconditional exact test methods are illustrated with real data from a neurological study. Empirical studies are conducted to investigate the performance of these and other test procedures with respect to size and power.
