In this paper, we define a new lifetime model called the Weibull-Dagum distribution. The R 2 values for the log‐logistic and lognormal distributions were around .62, which was greater than for the Weibull distribution. 3.1. Source [dpq]logis are calculated directly from the definitions. 4, pp. Introduction and motivation. The proposed model is based on the Weibull–G class (Bourguignon et al., 201416. Assume that each X r has a Dagum distribution. Basic properties of this distribution are presented For the VG, Dagum, and FX distributions, the w … For example, for ‚ = 0 we have the Dagum distribution. The Dagum distribution is widely used for income modeling in many countries all over the world (see for example Domanski and J˘edrzejczak [5], J˘edrzejczak [10]). References. X r/X 1 as the ratio of two Dagum r.v.’s It is possible to nu-merically find the distribution function of this r.v. ), Handbook of Income Distribution, pp. Google Scholar 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 parameter p of the Dagum distribution as defined by Kleiber and Kotz (2003). 1. (2000): Measurement of Inequality, in: Atkinson and Bourguignon (eds. r (r = 1, 2, …) describe the income of a household with r members. 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.) returns the Gini coefficient. 1 … Dagum distribution which is a sub-model of GB2 distribution plays an important role in size distribution of personal income. Cumulative Distribution Function (cdf) of EEDL Distribution. log-Dagum distribution de ned on the entire real line. The Dagum distribution has many good mathematical as well as statistical properties. Value. Some properties of the model including three di erent estimation procedures are … Advances in Econometrics, vol. Cowell, F.A. In this note, a new class of generalized Dagum distribution called gamma-Dagum distribution is presented. Gupta and Kundu [30] defined the pdf of rlogis uses inversion. The gamma-Dagum (GD) distribution which includes the gamma-Burr III (GB III), gamma-Fisk or gamma-log logis- The model contains many new sub-models: power logistic, linear log-Dagum, linear logistic and log-Dagum distributions among them. Recently, different distributions have been generalized using the T-R {Y} framework but the possibility of using Dagum distribution has not been assessed. Exponential-Dagum{Lomax}Distribution e six-parameter exponentiated-exponential-Dagum {Lomax} (EEDL) distribution is proposed and we derived someofitscharacterizations. 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. 167-227. Author(s) Alexander Sohn References. Therefore, we can estimate the para-meters λ r, β r, δ r. Now consider the r.v. ¡ï¬‚ ¶: (5) The transmuted Dagum distribution is very °exible model that approaches to difierent distributions when its parameters are changed. 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.
