Bonferroni-corrected p values
WebThe Bonferroni correction modifies probability (p) values to account for the increased likelihood of a “type I” error while doing numerous statistical tests. It employs Bonferroni … WebAug 21, 2024 · Before this step, I would like to adjust the p-values obtained in the regressions for multiple comparisons using the Bonferroni-Holm (BH) approach. I stored each of the adjusted models in a list and wrote a function to apply BH to my models as follows: summary (glht (model), test = adjusted ('holm'))

WebThe corrected p-value is calculated as the fraction of simulations having any p-value as good or better than the observed p-value. Comparison of simulation corrected p-values with Bonferroni corrected p-values actually suggests that the Bonferroni correction is not conservative enough.

WebNational Center for Biotechnology Information WebJul 23, 2024 · The Bonferroni correction compares a test statistic's p value out of m hypotheses to a nominal α by checking whether p < α m. Of course, you can alternatively modify the p values rather than α and check whether m p < α (yes, the term on the left can be greater than one). The Bonferroni correction is notoriously conservative.
