Webb提示一下,Fisher精确概率的计算比较耗时,在SPSS统计软件中,只在四格表卡方检验中默认输出此结果,而更大一些的R*C列联表卡方检验则需要用户手工设定输出参数,并耐心等待软件计算,软件默认是只等待5分 … WebbFisher's exact test is particularly appropriate when dealing with small samples. This section only covers test on a 2 by 2 table. That is, there are two variables, each has two categories. Comparing to the contingency chi-square test, Fisher's exact test is to exaclty calculate the p-value rather than being based on an asymptotic approximation.
