WebMar 24, 2024 · Fisher's exact test is a statistical test used to determine if there are nonrandom associations between two categorical variables. Let there exist two such variables X and Y, with m and n observed states, respectively. Now form an m×n matrix in which the entries a_(ij) represent the number of observations in which x=i and y=j. … WebI would like to calculate the odds ratio and corresponding p-value by fisher's exact test. After that, the odds ratio and p-value need to be added as another column in the table. ...

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. hellboy lore
