Since R version 3.5.0, this also increases the internal stack size which allows larger problems to be solved, however sometimes needing hours. In such cases, simulate.p.values=TRUE may be more reasonable.

WebFisher’s exact test is another test of association between the row and column variables. This test assumes that the row and column totals are fixed, and then uses the hypergeometric distribution to compute probabilities of possible tables conditional on the observed row and column totals. WebOne important thing to keep in mind here is that Fisher's exact test is typically implemented for contingency tables with fixed margins, i.e. the efficient algorithms utilized in Stata and …
