<b>RESUMEN</b><br> <br> El objetivo de este trabajo es el estudio de la desigualdad en la distribución personal de la<br> renta en España y por CC.AA. utilizando diversas especificaciones probabilísticas de carácter paramétrico. Se proponen dos modelos robustos para modelizar datos de renta usando la función...

Distributions with normal conditionals have biquadratic regression functions. Consequently, in contrast to classical bivariate normal distributions, their densities can be multimodal. Criteria for determining the number of modes are discussed and illustrations of representative multimodal...

In the risk theory context, let us consider the classical collective model. The aim of this paper is to obtain a flexible bivariate joint distribution for modelling the couple (S,N), where N is a count variable and S=X1+...+XN is the total claim amount. A generalization of the classical...
