nag_running_median_smoother (g10cac) computes a smoothed data sequence using running median smoothers.
The compound smoother 4253H, twice is recommended. The smoother 3RSSH, twice is popular when calculating by hand as it requires simpler computations and is included for comparison purposes.
Not applicable.
None.
The example program reads in a sequence of 49 data taken from
Tukey (1977), above. Results are obtained using the two smoothing methods described.
