From the Data Transforms and Smoothing guide there is a link to the Linear and Nonlinear Filters guide. Do any of these filter functions perform a LOESS or LOWESS filter on set of paired data? Searches for "loess" and "lowess" come up empty in Mathematica help but things sometimes go by another name. I really prefer the LOWESS filter over the LOESS filter.
If not, is there another function (maybe an image function) or would this have to be coded from scratch?
Some data to demonstrate the smoothing on:

for LOESS. I really want LOWESS though so I'll see what answers are posted. $\endgroup$ – Edmund Feb 10 '16 at 23:43
