Web14 aug. 2024 · The simplest definition of Locally Weighted Scatterplot Smoothing (LOWESS) is that it is a method of regression analysis which creates a smooth line through a scatterplot. This line provides a means to figure out relationships between variables. At the same time this line helps us understand trends of variables.
