Computational Statistics Aims and scope Submit manuscript

Summary

The number of mortgages in Spain is a counting process that can be modelled as a doubly stochastic Poisson process (DSPP). A modelling method for the intensity of a DSPP is proposed. A first step consists on estimating discrete sample paths of it from observed ones of the DSPP, then a continuous modelling is derived by means of Functional Principal Component Analysis. The method is validated by a simulation. Finally, it is applied to the real process of the mortgages in Spain discussing the interpretation of the principal components and factors.
