Simultaneous hypothesis testing
Multiple comparisons arise when a statistical analysis involves multiple simultaneous statistical tests, each of which has a potential to produce a "discovery." A stated confidence level generally applies only to each test considered individually, but often it is desirable to have a confidence level for the whole family of … Visa mer In statistics, the multiple comparisons, multiplicity or multiple testing problem occurs when one considers a set of statistical inferences simultaneously or infers a subset of parameters selected based on the … Visa mer If m independent comparisons are performed, the family-wise error rate (FWER), is given by $${\displaystyle {\bar {\alpha }}=1-\left(1-\alpha _{\{{\text{per comparison}}\}}\right)^{m}.}$$ Hence, unless the … Visa mer • q-value Key concepts • Family-wise error rate • False positive rate • False discovery rate (FDR) Visa mer The problem of multiple comparisons received increased attention in the 1950s with the work of statisticians such as Tukey and Scheffé.
