Fisher’s exact test for 2x2 contingency tables.
Performs Fisher’s exact test on a 2x2 contingency table. This test is particularly useful for small sample sizes where the chi-square approximation may not be valid.
Parameters: table: 2x2 array of observed frequencies (must be 2x2) alternative: Alternative hypothesis (default: “two-sided”) - “two-sided”: Test if association exists - “less”: Test if odds ratio < 1 - “greater”: Test if odds ratio > 1
Returns: Dictionary with: - odds_ratio: Odds ratio (ad)/(bc) - pvalue: P-value for the test
