Abstract

smgfit fits by ML the 3 parameter Dagum (Dagum, 1977,1980) distribution to a sample of counts or frequencies by income category. (For an estimator designed for unit record data, ssc desc dagumfit). 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.
