WebLET W = BIWEIGHT RES WEIGHTS W FIT Y = A+B*EXP(-C*X) An unweighted fit is performed first. Then the biweight transformation is applied to the residuals. These biweight transformed residuals are used as the weights in a weighted fit. Robust fits based on the biweight are part of a class of techniques called M-estimators of re gression.
