The proposed model is based on the WeibullâG class (Bourguignon et al., 201416. The Dagum distribution is widely used for income modeling in many countries all over the world (see for example Domanski and JËedrzejczak [5], JËedrzejczak [10]). Source [dpq]logis are calculated directly from the definitions. The Dagum distribution has many good mathematical as well as statistical properties. The generalized beta distribution of the second kind (GB2), McDonald [11], McDonald and Xu [12] is an important distribution with applications in finance and actuarial sciences, as well as economics, where Dagum distribution which is a sub-model of GB2 distribution plays an important role in size distribution of personal income. Dagum, C. (1985) Analysis of Income Distribution and Inequality by Education and Sex in Canada, in R. L. Basmann and G. F. Rhodes, Jr (eds.) rlogis uses inversion. 3.1. Dagum distribution which is a sub-model of GB2 distribution plays an important role in size distribution of personal income. log-Dagum distribution de ned on the entire real line. X r/X 1 as the ratio of two Dagum r.v.âs It is possible to nu-merically find the distribution function of this r.v. Value. Introduction and motivation. r (r = 1, 2, â¦) describe the income of a household with r members. In this note, a new class of generalized Dagum distribution called gamma-Dagum distribution is presented. The R 2 values for the logâlogistic and lognormal distributions were around .62, which was greater than for the Weibull distribution.

References. 4, pp. Therefore, we can estimate the para-meters Î» r, Î² r, Î´ r. Now consider the r.v. Basic properties of this distribution are presented The distribution function is a rescaled hyperbolic tangent, plogis(x) == (1+ tanh(x/2))/2, and it is called a sigmoid function in contexts such as neural networks. The model contains many new sub-models: power logistic, linear log-Dagum, linear logistic and log-Dagum distributions among them. Assume that each X r has a Dagum distribution. The gamma-Dagum (GD) distribution which includes the gamma-Burr III (GB III), gamma-Fisk or gamma-log logis- Google Scholar the parameter p of the Dagum distribution as defined by Kleiber and Kotz (2003). Recently, different distributions have been generalized using the T-R {Y} framework but the possibility of using Dagum distribution has not been assessed. 1 â¦ Cowell, F.A. The Dagum distribution Dagum [] was introduced as an attempt to overcome the limits of the Log-Normal and Gamma in modelling income distribution.This is mainly due to their poor ability to describe both upper and lower tails of the actual distributions which play a key role when income inequality is evaluated and for the design of income distribution policies. returns the Gini coefficient. Gupta and Kundu [30] deï¬ned the pdf of For example, for â = 0 we have the Dagum distribution. In this paper, we define a new lifetime model called the Weibull-Dagum distribution.
