Statistics.Test.Correction
Description
The more tests that are applied on a dataset, the more likely it becomes that a Type I error occurs (rejecting the null hypothesis when it is true). This module provides significance level corrections for repeated tests.

- bonferroni :: (Fractional f, Integral i) => f -> i -> f

Arguments
| :: (Floating f, Integral i) | |
| => f | Significance level |
| -> i | Number of comparisons |
| -> f | The corrected significance level |
Sidak correction: α* = 1 - (1 - α)^(1 / n), where α is the intended significance level over all tests, n the number of tests, and α* the corrected significance level.
