...oother for quite a while now, and for the matter of documentation I'd like to resolve the acronym LOESS. Unfortunately there's no explanation in the help file, and I didn't get anything convincing from google either. I know that the predecessor LOWESS stands for "Locally Weighted Scatterplot Smoothing". But what does LOESS stand for, specifically? "Locally Weighted Exponential Scatterplot Smoothing"? As far as I understand LOESS is still a local polynomial regression, so that would probably make no sense. Any help appreciated! Thanks in advance, Peter
