In this paper, a new lifetime distribution is proposed. Various statistical properties of the proposed such as survival function, hazard rate mean residual life moments, moment generating Bonferroni curve, Lorenz and order statistic are presented. The Bayesian estimator parameter derived. behavior assessed by simulation study. Furthermore, regression model developed based on distribution. Some ...

In earlier papers, classes of transfer policies have been studied and maximal and minimal Lorenz curves ( ) L p obtained. In addition, there are policies belonging to the class with given Gini indices or passing through given points in the ( ) p L , plane. In general, a transformation ( ) h x describing a realistic transfer policy has to be continuous. In this paper the results are generalized ...

The Lorenz attractor was introduced in 1963 by E. N. Lorenz as one of the first examples of strange attractors. However Lorenz’ research was mainly based on (non-rigourous) numerical simulations and, until recently, the proof of the existence of the Lorenz attractor remained elusive. To address that problem some authors introduced geometric Lorenz models and proved that geometric Lorenz models ...

This paper shows how the Lorenz curve can be used, together with models of disease risk, to allocate scarce resources so as to optimize a health benefit. Consider the example of breast cancer mortality. If there were sufficient resources to provide all women with mammograms, a certain maximal number of lives could be saved. Suppose, however, that only a fraction of that amount of money is avail...

Finding the best location is the first and most fundamental step in planning for offering a service or product to costumers. To locate appropriate location, scholars have suggested a variety of models based on circumstances and conditions. Equality is of importance in locating models in the utility sector and in making equal accessibility to urban utilities for members of the society; it has an...

Sanjiang Plain has undergone dramatic land degradation since the 1950s, which has caused negative effects on ecosystems services and sustainability. In this study, we used trajectory analysis as well as the Lorenz curve, Gini coefficient and relative land use suitability index (R) to analyze spatiotemporal changes of land degradation from 1954 to 2013 and to make a preliminary estimation of the...

The paper reviews the “κ-generalized distribution”, a statistical model for analysis of income data. Basic analytical properties, interrelationships with other distributions, and standard measures inequality such as Gini index Lorenz curve are covered. An extension basic that best fits wealth data is also discussed. new old empirical evidence presented in article shows κ-generalized income/weal...
