LOESS / LOWESS Lokal Regression

LOESS (lokalt estimeret scatterplot-udjævning), introduceret af William Cleveland i 1979 og udvidet med Susan Devlin i 1988, tilpasser en glat kurve gennem data ved at udføre en separat vægtet polynomiel regression i nærheden af hvert punkt. Nærliggende observationer tæller mere end fjerne, så metoden følger lokal struktur uden at antage nogen global funktionel form, hvilket gør den til en populær eksplorativ udjævner for scatterplots.
