- scikit_posthocs.global_f_test(p_vals: Union[List, ndarray], stat: bool = False) Union[float, Tuple[float, float]] ¶
Fisher’s combination test for global null hypothesis.
Computes the combined p value using chi-squared distribution and T statistic: -2 * sum(log(x)) 1.
- Parameters
p_vals (Union[List, ndarray]) – An array or a list of p values.
stat (bool) – Defines if statistic should be returned.
- Returns
p_value (float) – Global p value.
t_stat (float) – Statistic.
