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 ...

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.

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 ...

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.

Functional Form for Estimating the Lorenz Curve

open access: yesAmerican Finance & Banking Review, 2019
A flexible Lorenz curve which offers different curvatures allowed by the theory of income distribution is introduced. The intrinsically autoregressive nature of the errors in cumulative data of the Lorenz curve is also under consideration.

Estimating Lorenz Curve for Iran by Using Continuous L1 Norm Estimation

open access: yesInternational Journal of Marketing Research Innovation, 2019
In this paper, the L1 norm of continuous functions and corresponding continuous estimation of regression parameters are defined. The continuous L1 norm estimation problem of one and two parameters linear models in the continuous case are solved.
