WitrynaIf it > 1, then further weighted local linear regressions are performed, where the weights are the same as above times the _lowess_bisquare function of the residuals. Each iteration takes approximately the same amount of time as the original fit, so these iterations are expensive. They are most useful when the noise has extremely heavy … Witrynathe linear space of polynomials of degree @. 3.2 Fitting local polynomials We will now define the recipe to obtain a loess smooth for a target covariate 3. ...
