Lowess smoother是什么
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 … WebLOWESS regression Locally weighted regression and smoothing scatter plots or LOWESS regression was introduced to create smooth curves through scattergrams. LOWESS regression is very similar to Kernel regression as it is also based on polynomial regression and requires a kernel function to weight the observations.
