Otherwise, you can impose equality constraints across models and condcut X2 dif-test with df=1 (with / without constraints). … WebWhen considering several hypotheses, the problem of multiplicity arises: the more hypotheses are checked, the higher the probability of obtaining Type I errors (false positives). The Holm–Bonferroni method is one of many approaches for controlling the FWER, i.e., the probability that one or more Type I errors will occur, by adjusting the ...
Webthe maximum overall rate of Type I error for multiple tests of significance assessed within an experiment. Later in the history of methods for controlling the overall rate of Type I … WebFirst, Bonferroni's correction is introduced as a way of controlling the probability of at least one type I error (the familywise error rate) when testing multiple hypotheses. ANOVA (analysis of variance) is described, which enables the hypothesis of a common mean to be tested about multiple groups of univariate data.
