WebApr 1, 2012 · The Bonferroni correction is based on the idea that if an experimenter is testing n dependent or independent hypotheses on a set of data, the probability of type I error is offset by testing each hypothesis at a statistical significance level 1/ n times what it would be if only one hypothesis were tested. WebThe Bonferroni correction for a chi-square analysis is the number of comparisons being …

With respect to FWER control, the Bonferroni correction can be conservative if there are a large number of tests and/or the test statistics are positively correlated. The correction comes at the cost of increasing the probability of producing false negatives, i.e., reducing statistical power. There is not a definitive consensus on how to define a family in all cases, and adjusted test results may vary depending on the number of tests included in the family of … WebA p-value threshold (alpha) of 0.05 yields a FPR of 5% among all truly null features.
