El clásico modelo de valoración de opciones europeas de Black y Scholes (1973) supone que los retornos logarítmicos de un activo financiero se distribuyen normalmente, no obstante varios estudios empíricos muestran, primero, que esta distribución puede ser asimétrica y tener colas pesadas"...

Testing for the assumption of independence between spatial variables is an important first step in spatial conometrics. Usually the researchers use the bivariate generalization of the Moran’s statistic, specifying a spatial matrix a priori. This test is applicable only to detect linear...

In this paper we introduce two general non-parametric first-order stationary time-series models for which marginal (invariant) and transition distributions are expressed as infinite-dimensional mixtures. That feature makes them the first Bayesian stationary fully non-parametric models developed...
