Tau (τ) Estimator af Regression

Tau-estimatoren er en robust lineær regressionsmetode introduceret af Yohai og Zamar i 1988, der tilpasser modellen ved at minimere en effektiv τ-skala af residualerne. Den bygger på skalaestimatet fra S-estimatoren for at kombinere et højt breakdown point med høj statistisk effektivitet og bruges ofte som et alternativ til MM-estimatoren i små stikprøver.
