Is it possible to do LOESS smoothing on equally spaced data using convolution?
The Wikipedia article on LOESS mentions a possibility of using a FIR filter for LOESS. I could not find anything more about it, though.
I'm currently using
in Python but it's slow. I tried switching to a Savitzky-Golay smoothing filter but I could not get comparable results on my data.
I mostly use this for detrending.
