- SMOOTH reads pairs of numbers (x- and y-values) from the standard input
- (or the given file), fits a smooth curve to the points, and writes to
- the standard output points from the smooth curve. By default, the
- curve is calculated using the "lowness" procedure developed by W. S.
- Cleveland (see below). This technique achieves robustness by
- decreasing weights on data points which are far from the fitted line.
- An alternate procedure called "split linear smoothing" due to Art Owen
- is also provided (with the -s switch). This technique smooths the data
- while preserving sharp discontinuities in slope or value.
