WebAug 5, 2024 · Fisher Score: The key idea of Fisher score is to find a subset of features, such that in the data space spanned by the selected features, the distances between data points in different classes are as large as possible, while the distances between data points in the same class are as small as possible. WebNov 29, 2024 · The common wisdom is that Fisher’s method tend to values low p-values, instead of consistently low p -values. An alternative to Fisher’s method is Stouffer’s method. The idea is to transform the p -values to z -scores, then compute a combined z -score by averaging the individual z -scores. eaglefielddrags.com
