Nella LDA, la distribuzione dei predittori \(X\) è modellata separatamente in ciascuna delle classi della variabile di risposta (cioè. \(Y\)), e quindi, tramite il teorema di Bayes, è usata per convertire queste distribuzioni in stime per \(Pr(Y = k X = x)\), chiamate “probabilità a posteriori”.Più specificatamente, il teorema di …

Web5 jan. 2024 · LDA (Linear Discriminant Analysis) is used when a linear boundary is required between classifiers and QDA (Quadratic Discriminant Analysis) is used to find a non-linear boundary between classifiers. LDA and QDA work better when the response classes are separable and distribution of X=x for all class is normal. A displaced threshold affects only the LDA for approaches made to that threshold; all declared distances for operations in the reciprocal direction are unaffected. Figures A-1 (B) through A-1 (D) illustrate a runway provided with a clearway or a stopway or having a displaced threshold.
