Robust Faktor Analyse

Robust Faktor Analyse reetablerer den latente faktorstruktur af multivariat kontinuerlige data, mens den modstår den forvrængende påvirkning fra outliers. Introduceret af Pison, Rousseeuw, Filzmoser og Croux (2003), erstatter den den klassiske stikprøvekovarians med en robust estimator såsom Minimum Covariance Determinant (MCD) eller en S-estimator, før faktorerne ekstraheres.
