Assessing spatial inequality in cancer service access in regional areas

open access: yesCogent Public Health, 2022
This paper applies economic concepts from measuring income inequality to an exercise in assessing spatial inequality in cancer service access in regional areas. We propose a mathematical model for accessing chemotherapy among local government areas (LGAs)

Income inequality measures and the middle class [PDF]

open access: yesSHS Web of Conferences, 2021
We study how the presence of the middle class in the sense of Gevorgyan-Malykhin affects the value of income inequality measures including the Gini coefficient J and the Hoover index H.

An Exponential Family of Lorenz Curves [PDF]

open access: yesSouthern Economic Journal, 2001
A new method for building parametric‐functional families of Lorenz curves, generated from an initial Lorenz curve (which satisfies some regularity conditions), is presented. The method is applied to the exponential family since they use the exponential Lorenz curves as their generating curves.

An alternative method to test scale invariance

open access: yesMethodsX, 2020
We introduce an alternative method that is simple and can be used to test scale invariance or self-similarity in any types of data, irrespective of their distributions.

Cascade of Invariant Curve Doubling Bifurcations and Quasi-Periodic Hénon Attractor in the Discrete Lorenz-84 Model [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Физика, 2020
Background and Objectives: Chaotic behavior is one of the fundamental properties of nonlinear dynamical systems, including maps. Chaos can be most easily and reliably diagnosed using the largest Lyapunov exponent, which will be positive for the chaotic ...

Development of an Impairment Point in Time Probability of Default Model for Revolving Retail Credit Products: South African Case Study

open access: yesRisks, 2021
A new methodology to derive IFRS 9 PiT PDs is proposed. The methodology first derives a PiT term structure with accompanying segmented term structures. Secondly, the calibration of credit scores using the Lorenz curve approach is used to create account ...

Application of Lorenz-curve model to stratified water injection evaluation

open access: yesPetroleum Exploration and Development, 2015
To evaluate the effect of stratified water injection accurately during different development stages, a Lorenz-curve model was constructed upon a modified four-parameter Sarabia-Lorenz-curve model with water injectivity test data over years, and the ...
