Alternatives of Fisher

WebOne major drawback of Fisher's exact test is that for large tables (or large samples) it becomes computationally ineffective. G-test Another alternative is the so-called G-test. Its statistic is also approximately chi-squared distributed, but for small samples, this approximation is closer than one that chi-squared test uses. WebApr 16, 2024 · With the Exact Tests module installed, the Crosstabs procedure can print the Fisher-Freeman-Halton exact test of independence when the contingency table is larger than 2x2.

In that case, the null hypothesis tested by Fisher's test can be formulated as both the ORs being equal to 1. You could calculate the ORs by splitting into two 2 × 2 tables, or simply by using a logistic regression, where the coefficents (forget the intercept) are log odds ratios.

WebFisher's exact test is used to calculate P values for small sample sizes. It was created for a specific (and rare) experimental design where marginal totals are fixed. It's called an exact test, but that can be misleading because it's only exact if your experiment meets that condition . Yates' continuity correction can be used alongside chi-square.
