提出了匹配和不匹配情况下2×2表的随机化模型，并证明了通常的大样本统计检验是保守的。讨论了不匹配情况下的似然曲面。在匹配的情况下，该模型比更常见的概率模型更明确地考虑了试验中使用的匹配标准的影响。在连续测量的情况下给出了一个简单的类比。
Randomization models for 2 × 2 tables in the matched and unmatched cases are proposed and, in terms of these models, the usual large sample statistical tests are shown to be conservative. The likelihood surface for the unmatched case is discussed. In the matched case, the model takes more explicit account of the effect of the matching criteria used in the trial than do the more familiar probability models. A simple analogue in the case of continuous measurements is indicated.
