When To Use Fisher’s Exact Test - USTC
WebPROC FREQ provides exact tests for the Pearson chi-square, the likelihood-ratio chi-square, and the Mantel-Haenszel chi-square (in addition to Fisher’s exact test). PROC FREQ also provides an exact chi-square goodness-of-fit test for one-way tables. You can request these exact tests by specifying the corresponding options in the EXACT statement. WebSep 18, 2024 · You get the strange p-value=1 and OR=0 because one or more of your counts is 0. It should not be computed by the chi-square equation, which through multiplication yields chi-values of 0 for these … Web1.
