WebThe odds of you getting a false positive result when running just 20 tests is a whopping 64.2%. This figure is obtained by first calculating the odds of having no false discoveries at a 5% significance level for 20 tests: The probability 20 trials will not have any false conclusions (using the binomial formula). If the probability of having no false conclusions … WebThe q -value can be interpreted as the false discovery rate (FDR): the proportion of false positives among all positive results. Given a set of test statistics and their associated q -values, rejecting the null hypothesis for all tests whose q -value is less than or equal to some threshold ensures that the expected value of the false discovery ... WebDefinition. The false positive rate is = +. where is the number of false positives, is the number of true negatives and = + is the total number of ground truth negatives..

Part of the reason you're confused may be that you are considering the special case that all null hypotheses are true (i.e. m = m0 ). When all null hypotheses are true, the FWER and FDR are indeed the same. For m independent tests of true null hypotheses, FDR = FWER = 1- (1-alpha)^ m. The difference comes when some null hypotheses are ...

The false positive rate (FPR) is the proportion of all negatives that still yield positive test outcomes, i.e., the conditional probability of a positive test result given an event that was not present. The false positive rate is equal to the significance level. The specificity of the test is equal to 1 minus the false positive rate. In statistical hypothesis testing, this fraction is given the Greek letter α, and 1 − α is defined as t… http://genomics.princeton.edu/storeylab/papers/Storey_FDR_2011.pdf
