Bonferroni corrected

WebThe Bonferroni/Sidak corrections are very consecutive, protecting against type 1 error at the expense of increasing type 2 error. The corrections assumes independent tests, this assumption is usually incorrect. If some of the tests have some dependencies the Bonferroni/Sidak corrections would be over protection. WebNov 1, 2004 · Bonferroni corrections are employed to reduce Type I errors (i.e., rejecting Ho when Ho is true) when multiple tests or comparisons are conducted. Two kinds of Bonferroni procedures are commonly used.

WebFeb 24, 2024 · For the Bonferroni correction this is easy enough. If your α level is 0.05, then you divide this by the number tests, which then is your new Bonferroni adjusted α -level. In your case 0.05 / 24 = 0.00208. As you can see, none of your raw.p 's make that cut-off. So your output makes sense. WebThere is an important difference between Bonferroni* (FWER/Family-wise-error rate) and Benjamini* (FDR/False discovery rate).
