Sidak
Sidak is a surname of European origin and may also refer to a statistical method known as Sidak's correction. In statistics, Sidak's correction is used to adjust p-values when multiple hypothesis tests are conducted in order to control the familywise error rate. The adjusted p-value is computed as p_adj = 1 − (1 − p)^m, where p is the observed p-value and m is the number of simultaneous tests. Sidak's correction is less conservative than the Bonferroni correction when the tests are independent, but its validity relies on an independence assumption; under dependency it can be more liberal. Because of this, researchers choose the method based on the structure of their data and the desired balance between Type I and Type II error rates. The approach is commonly applied in fields with large numbers of tests, such as genetics, neuroimaging, and other high-throughput studies.
