WebIn Huber weighting, observations with small residuals get a weight of 1 and the larger the residual, the smaller the weight. This is defined by the weight function w ( e) = { 1 for e ≤ k k e for e > k With bisquare weighting, all cases with a non-zero residual get down-weighted at least a little.
