Thirty years of progeny from Chao's inequality : estimating and comparing richness with incidence data and incomplete sampling / Chao, Anne (National Tsing Hua University (Taiwan). Institute of Statistics) ; Colwell, Robert K. (University of Connecticut. Department of Ecology and Evolutionary Biology)
In the context of capture-recapture studies, Chao (1987) derived an inequality among capture frequency counts to obtain a lower bound for the size of a population based on individuals' capture/non-capture records for multiple capture occasions. [...]

On a property of Lorenz curves with monotone elasticity and its application to the study of inequality by using tax data / Sordo Díaz, Miguel Ángel (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa) ; Berihuete Macías, Ángel (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa) ; Ramos González, Carmen Dolores (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa) ; Ramos Romero, Héctor Manuel (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa)
The Lorenz curve is the most widely used graphical tool for describing and comparing inequality of income distributions. In this paper, we show that the elasticity of this curve is an indicator of the effect, in terms of inequality, of a truncation of the income distribution. [...]

Comparison of two discrimination indexes in the categorisation of continuous predictors in time-to-event studies / Barrio Beraza, Irantzu (Universidad del País Vasco. Departamento de Matemáticas) ; Rodríguez-Álvarez, María Xosé (Universidade de Vigo. Departamento de Estatística e Investigación Operativa) ; Meira-Machado, Luis (Universidade do Minho (Braga, Portugal). Centre of Mathematics and Department of Mathematics and Applications) ; Esteban, Cristóbal (Hospital de Galdakao (Usansolo, Biscaia)) ; Arostegui, Inmaculada (Universidad del País Vasco. Departamento de Matemáticas)
The Cox proportional hazards model is the most widely used survival prediction model for analysing time-to-event data. To measure the discrimination ability of a survival model the concordance probability index is widely used. [...]

Bayesian correlated models for assessing the prevalence of viruses in organic and non-organic agroecosystems / Lázaro, Elena (Universitat de València. Departament d'Estadística i Investigació Operativa) ; Armero, Carmen (Universitat de València. Departament d'Estadística i Investigació Operativa) ; Rubio, Luis (Instituto Valenciano de Investigaciones Agrarias)
Cultivation of horticultural species under organic management has increased in importance in recent years. However, the sustainability of this new production method needs to be supported by scientific research, especially in the field of virology. [...]

Goodness-of-fit test for randomly censored data based on maximum correlation / Strzalkowska-Kominiak, Ewa (Cracow University of Technology (Polònia). Mathematical Institute) ; Grané, Aurea (Universidad Carlos III de Madrid. Departamento de Estadística)
In this paper we study a goodness-of-fit test based on the maximum correlation coefficient, in the context of randomly censored data. We construct a new test statistic under general right- censoring and prove its asymptotic properties. [...]

A quadtree approach based on European geographic grids : reconciling data privacy and accuracy / Lagonigro, Raymond (Universitat de Vic. Departament d'Economia i Empresa) ; Oller Piqué, Ramon (Universitat de Vic. Departament d'Economia i Empresa) ; Martori, Joan Carles (Universitat de Vic. Departament d'Economia i Empresa)
Methods to preserve confidentiality when publishing geographic information conflict with the need to publish accurate data. The goal of this paper is to create a European geographic grid frame- work to disseminate statistical data over maps. [...]

Statistical modeling of warm-spell duration series using hurdle models / Rydén, Jesper (Uppsala University. Department of Mathematics)
Regression models for counts could be applied to the earth sciences, for instance when studying trends of extremes of climatological quantities. Hurdle models are modified count models which can be regarded as mixtures of distributions. [...]
