From: Interpreting a Bayesian phase II futility clinical trial
 | Should not reject \(H_0\) | Should reject \(H_0\) |
---|---|---|
Fail to reject \(H_0\) | No error | Type II error—we are unable to rule out the futility of a treatment for which futility should be declared. |
Reject \(H_0\) | Type 1 error—we label a treatment as futile relative to control which should not be labeled as futile. | No error |
