WebSo another correction is the Sidak Correction, which has this extra condition where the tests need to be independent. So even though we talked about in the last slide that in order to make that plot, we were assuming that they were independent, but the Bonferonni Correction in general does not need to assume that. Webcorrected alpha for Sidak method. alphacBonf float. corrected alpha for Bonferroni method. Notes. There may be API changes for this function in the future. Except for ‘fdr_twostage’, the p-value correction is independent of the alpha specified as argument. In these cases the corrected p-values can also be compared with a different alpha.
