SMGFIT: Stata module to fit a Singh-Maddala distribution to grouped data via ML
Statistical Software Components from Boston College Department of Economics
smgfit fits by ML the 3 parameter Singh-Maddala (1976) distribution to a sample of counts or frequencies by income category. (For an estimator designed for unit record data, ssc desc smfit). Optionally specified variables z1var and z2var encode the lower and upper limits of each interval; if they are not specified, variables serving that role and called z1 and z2 are assumed to exist.
Requires: Stata version 8.2
Keywords: Singh-Maddala; income distribution; multinomial maximum likelihood; grouped; interval; censored (search for similar items in EconPapers)
