Robust beta
WebA robust estimation method is a compromise with respect to these three features. This compromise is illustrated by Anscombe and Guttman ( 1960) using an insurance metaphor: “sacrifice some efficiency at the model in order to insure against accidents caused by deviations from the model”.
