- solas_disparity.statistical_significance.fishers_or_chi_squared(...)#
Conduct either a Fisher’s exact test or a chi-squared test. If max_for_fishers is greater than any value of the expected or observed contingency table, the Fisher’s exact test is conducted. Else, the chi-squared test is conducted.
- Parameters
group_data (DataFrame) – Dataframe containing columns for group data.
protected_groups (List[str]) – List of protected groups.
reference_groups (List[str]) – List of reference groups with the same length as
protected_groups.group_categories (List[str]) – List of group categories to which each protected and reference group pair belongs to (e.g. race, gender, age, etc.). Has the same length as
protected_groups.outcome (Series) – Outcome series.
sample_weight (Optional[pd.Series], optional) – Sample weight series. Has the same length as
group_data. Defaults to None.max_for_fishers (Union[int, float], optional) – Maximum value of samples for Fisher’s exact test to be used. Defaults to const.MAX_FOR_FISHERS.
- Returns
Statistical significance result object.
