Questions tagged [smoothing]

Smoothing related to statistical programing solutions in which a signal is filtered to create an approximating function that attempts to capture important patterns in the data, while leaving out noise, or for visual clarity to see general trends.

In scientific software for statistical computing and graphics, function smooth.spline implements a smoothing spline; function ksmooth implements a kernel estimator; function loess implements LOESS.
