WebLOWESS is an acronym for Locally Weighted Scatterplot Smoothing, whereby multiple regressions are fitted over different regions of the data domain and then combined based on weightings linked to the distance between the prediction point and the data used to fit each of the local regressions.

WebDetails. Fitting is done locally. That is, for the fit at point x, the fit is made using points in a neighbourhood of x, weighted by their distance from x (with differences in ‘parametric’ variables being ignored when computing the distance). The size of the neighbourhood is controlled by α (set by span or enp.target ). WebA lowess smoother generally works best when the fraction (f) of points is large enough to give a smooth fit without distorting the underlying relationship between the variables. …
