Abstract

Following the continuous modelling of loss index triggers for CAT Bonds developed by Pérez-Fructuoso (2008 and 2009), this paper estimates the instantaneous loss reporting rate (the proposed model’s fundamental parameter) by applying a Restricted Minimum Squares’ alternative methodology to a dataset of several floods occurred in Spain. Results are compared with those stemming from the traditional methodology of maximum-likelihood, the Wiener-Process-induced model’s volatility is obtained, and the goodness-of-fit is verified through the calculation of the corresponding confidence intervals.
