DISSIM: Stata module to calculate dissimilarity index

Nicholas Cox

Statistical Software Components from Boston College Department of Economics

Abstract: dissim displays the dissimilarity index D for each pair of variables in varlist. If x and y are >= 0, form the proportions p = x / SUM x and q = y / SUM y and calculate D = 1/2 SUM ( | p - q | ). D lies in [0, 1]. Update 2021: The original dissim.* files from 19990108 remain here as a matter of record, but anyone henceforth downloading this is recommended to use the dissim_index.* files, as calls to the help for dissim now link to a official Stata help file.
