WebIt is sometimes called a Fisher Irwin test. It is given this name because it was developed … WebOct 17, 2024 · What I meant with my statement is that the application of Fisher’s exact test to larger tables is not as straightforward as the chi-squared test. When the dimensionality exceeds 2x2, Fisher’s exact test quickly becomes computationally infeasible. Then, the p-value cannot be calculated exactly anymore but one has to resort to Monte Carlo ...
