WebDescription. The classical Sidak correction returns adjusted p-values, ensuring strong FWER control under the assumption of independence of the input p-values. It only uses the fact that the probability of no incorrect rejection is the product over true nulls of those marginal probabilities (using the assumed independence of p-values).
