SAS - Fishers 精确检验

WebbThat's funny. SAS calculates the Fisher's exact test p-value the exact way, by enumerating the hypergeometric probability of every single table in which the odds ratio is at least as big or bigger in favor of the alternative hypothesis. There's probably a way for me to calculate how many tables that is, but knowing that it's big enough to slow SAS down is enough.

Hi, I was running proc freq for one categorical variable and a list of categories variables without specifying options "chisq" or "exact", and found SAS only print out chisq table for some variable but print out both chisq & fisher exact tables though no expected values in cells less than 5. WebbThe Fisher Exact test in SAS is a test of significance that is used in the place of chi-square test SAS in 2 by 2 tables, especially in cases of small samples. If the assumptions for using the chi-square test are not met (i.e., small expected numbers in one or more cells), then an alternative hypothesis test to use is Fisher exact test.
