This paper proposes a variant of a threshold stochastic conditional duration (TSCD) model for financial data at the transaction level. It assumes that the innovations of the duration process follow a threshold distribution with a positive support. In addition, it also assumes that the latent...

¿Cómo se combinan las densidades predictivas para mejorar las predicciones? En el presente trabajo se propone una serie de estimadores consistentes ponderados, los cuales proporcionan combinaciones de densidad de predicción que aproximan el valor real de la densidad predictiva, condicionado...
