Description Readers' comments

A common practice to analyze income data is to fit a model to data and then compute all the inequality indices that appear useful as functions of the estimated shape parameters. In a sense, the choice of the probability distribution and the choice of the inequality index are independent. This paper develops a technique, based on Q-Q plot, that is useful for the identification of both the model for the size distribution of incomes and the measure of economic inequality.

Keywords: order statistics, direct search estimates, correlation coefficient, simulation.
