Abstract

In this paper, Weibull two-parameter and beta three-parameter models, Lognormal, gamma and Dagum are estimated by Maximum Likelihood Estimation (MLE) annually and using the data of Iranian Household income and expense during 1982-2011 via VGAM in R software package subprogram calculator. The comparison of these models will be done by Akaike Information Criterion (AIC). According to AIC and the charts of the probability density functions, it is clear that Degum distribution function has a good fit. Estimated parameters of beta and delta are increasing and alpha parameter is declining during these years.
