What is the Family-wise Error Rate? - Statology
Sep 14, 2020 · The formula to estimate the family-wise error rate is as follows: Family-wise error rate = 1 – (1-α) n. where: α: The significance level for a single hypothesis test; n: The total number of tests; For example, suppose we conduct 5 different comparisons using an alpha level of α = .05. The family-wise error rate would be calculated as ...
Familywise Error Rate (Alpha Inflation): Definition
What is the Familywise Error Rate? The familywise error rate (FWE or FWER) is the probability of a coming to at least one false conclusion in a series of hypothesis tests . In other words, it’s …
4.2 - Controlling Family-wise Error Rate | STAT 555 - Statistics …
Pr(V > 0) is called the family-wise error rate or FWER. It is easy to show that if you declare tests significant for \(p < \alpha\) then FWER ≤ \(min(m_0\alpha,1)\). The most commonly used method which controls FWER at level \(\alpha\) is called Bonferroni's method.

A primer on strong vs weak control of familywise error rate
Part of the confusion stems from a powerful technique called the closed testing principle, whose statement is deceptively simple, but is sometimes misinterpreted. This primer presents a straightforward way to think about multiplicity adjustment.
Controlling the family-wise error rate in multi-arm, multi-stage …
In this paper we provide an analytical method for calculating the family-wise error rate for a multi-arm, multi-stage trial and highlight the potential for considerable error rate inflation in uncontrolled designs.
Family-wise error rate - (Data Science Statistics) - Fiveable
The family-wise error rate (FWER) is the probability of making one or more false discoveries when conducting multiple hypothesis tests. This concept is crucial in statistical analysis, as performing multiple tests increases the chance of incorrectly rejecting the null hypothesis at least once.
