WebFeb 16, 2024 · A Bonferroni Correction refers to the process of adjusting the alpha (α) level for a family of statistical tests so that we control for the probability of committing a type I error. The formula for a Bonferroni Correction is as follows: αnew = αoriginal / n where: αoriginal: The original α level WebA p-value threshold (alpha) of 0.05 yields a FPR of 5% among all truly null features.
