TDDENS: Stata module to estimate and graph bivariate density with heat map
Statistical Software Components from Boston College Department of Economics
tddens estimates bivariate density using a symmetric triangle kernel with bandwidth given as a proportion of sample range (default 10%) and produces several graphs. A "heat map" is produced by default; option sgraph shows a surface plot as points, and option bgraph shows a bar graph that offers an alternative view of the surface.
Requires: Stata version 8.2
Keywords: bivariate density; kernel density; heat map; surface plot (search for similar items in EconPapers)
