Fishers 2x2
WebOPTION FISHER, more specifically performs Fisher's exact test which is an exact test only for a 2 × 2 table in SAS. The basic idea behind exact tests is that they enumerate all possible tables that have the same margins, e.g., row sums and column sums. WebColumn Total. a+c. b+d. a+b+c+d. In the case of a 2x2 matrix, you can calculate the p-value of the test by summing all the p-values which are less than the conditional probability of the actual matrix. Thus, p cutoff. For this example, the sum of the p-values that are less than or equal to the p cutoff for the other possible matrices is 0.0054775.
