WebOttawa Subarachnoid Hemorrhage (SAH) Rule for Headache Evaluation. Rules out SAH in patients with headache. WebDescription. Fisher Score (Fisher 1936) is a supervised linear feature extraction method. For each feature/variable, it computes Fisher score, a ratio of between-class variance to within-class variance. The algorithm selects variables with largest Fisher scores and returns an indicator projection matrix.
