ADJKSM: Stata module to perform adjusted "ksm" for robust scatterplot smoothing
Isaías Hazarmabeth Salgado-Ugarte Makoto Shimizu
Statistical Software Components from Boston College Department of Economics
adjksm calculates locally weighted regression scatterplot smoothing with an uniform band width along the x interval by a modification of the original ksm Stata ado-file. The robust iterative procedure is implemented in two additional modified ado-files: lorobwei and roblowes. This is an updated version of that published in STB-25 and STB-26, with corrections to enable use in Stata version 7.0.
Requires: Stata version 3.0
Keywords: kernel density; smoothing; scatterplot; robust (search for similar items in EconPapers)
Note: This module may be installed from within Stata by typing "ssc install adjksm". Windows users should not attempt to download these files with a web browser.
