Indflydelsesdiagnostik (Cook's Distance, DFFITS, Leverage)

Indflydelsesdiagnostik er en familie af post-fit-mål, der kvantificerer, hvor meget hver enkelt observation påvirker en tilpasset regression. Cook's distance blev introduceret af R. Dennis Cook i 1977, mens leverage og DFFITS blev formaliseret af Belsley, Kuh og Welsch i 1980, for at markere de observationer, der mest kraftigt trækker i de estimerede koefficienter.
