Revisiting "A universal model for the Lorenz curve with novel applications''
José María Sarabia, Vanesa Jordá, Mercedes Tejería +1
This research reviews several crucial aspects of the universal model for the Lorenz curve proposed by Sitthiyot and Holasut (2023) (hereafter, SH (2023)). A first issue concerns th…
Multiple integral representations of the Catalan's constant
Emilio Gómez-Déniz, José María Sarabia
In this paper, we present several novel integral representations of Catalan's constant. We begin by deriving an initial result expressed as a double integral. Subsequently, as a co…
Beyond the Beta Lorenz Curve: A New Parametric Family for Poverty and Inequality Estimation
José María Sarabia, Vanesa Jordá, Emilio Gómez-Déniz
The estimation of inequality and poverty measures is frequently constrained by a lack of individual data. When only income shares are available, the Beta Lorenz curve introduced by…
Aggregation of Dependent Risks in Mixtures of Exponential Distributions and Extensions
José María Sarabia, Emilio Gómez-Déniz, Faustino Prieto +1
The distribution of the sum of dependent risks is a crucial aspect in actuarial sciences, risk management and in many branches of applied probability. In this paper, we obtain anal…
Simulating Posterior Distributions for Zero-Inflated Automobile Insurance Data
J. M. Pérez-Sánchez, E. Gómez-Déniz
Generalized linear models (GLMs) using a regression procedure to fit relationships between predictor and target variables are widely used in automobile insurance data. Here, in the…
Risks aggregation in multivariate dependent Pareto distributions
José María Sarabia, Emilio Gómez-Déniz, Faustino Prieto +1
In this paper we obtain closed expressions for the probability distribution function, when we consider aggregated risks with multivariate dependent Pareto distributions. We work wi…
Modelling Road Accident Blackspots Data with the Discrete Generalized Pareto distribution
Faustino Prieto, Emilio Gómez-Déniz, José María Sarabia
This study shows how road traffic networks events, in particular road accidents on blackspots, can be modelled with simple probabilistic distributions. We considered the number of…
