We extend the prequential approach introduced by A. P. Dawid to continuous time marked point processes. A prequential forecasting system is expressed by means of the stochastic intensities of the point process. The exact independence and 1-exponentiality of the derived compensators are used to assess the predictive performance of the model and the inferential procedure.
Key Words: Bayesian inference Goodness of fit Marked point process Markov chain Monte Carlo Prequential analysis
