fisher exact test statistic valueFisher确切检验(Fisher's Exact Test)的统计值(statistic value)是用于衡量两个分类变量之间关联性的一个数值。这个统计值是根据Fisher确切检验的计算公式得出的,它考虑了样本数据的所有可能组合,并计算出一个p值,用于判断两个分类变量之间是否存在显著关联。 需要注意的是,Fisher确切...
那个warning意思是说有四分之一（25%）的格子理论数小于5.这是做一般卡方检验和Fisher's Exact Test的检验条件，不满足就要用Fisher's Exact Test。Two-sided是双侧P值，一般都是这个。除非你的专业要求不同，会使用单侧概率。

One is the widely taught Pearson chi-square test, which uses the well-known 2statistic. The chi-square test is appropriate for large sample inference, and it is equivalent to the Z-test that uses the difference between the two sample proportions for the 2 2 case. Another method is Fishers...
where Fi:n⁎:n is the cumulative distribution function of the progressively Type-II censored order statistic Xi:n⁎:n from a standard exponential distribution. In fact, expression (8.32) shows that the gain of information using the Type-II hybrid censoring procedure is given by 1ϑ2∑i=...

The property that where a sufficient statistic exists, the likelihood, apart from a factor independent of the parameter to be estimated, is a function only of the parameter and the sufficient statistic, explains the principle result obtained by Neyman and Pearson in discussing the efficacy of tests...
parameter value was certainly a critical step for theoretical statistics [see, e.g., Geisser (1975), footnote on p. 320 and Stigler (1976)]. In fact, Fisher attributed the neglect of theoretical statistics not only to this failure in distinguishing between parameter and statistic but also to...
