Bonferroni step-down holm correction
WebFeb 16, 2024 · The formula for a Bonferroni Correction is as follows: αnew = αoriginal / n. where: αoriginal: The original α level. n: The total number of comparisons or tests being performed. For example, if we perform three statistical tests at once and wish to use α = .05 for each test, the Bonferroni Correction tell us that we should use αnew = .01667. http://ammoniaindustry.com/sq24sp/bonferroni-correction-python
