摘要：

.there are growing concerns for reserves estimation of Incurred But NotReported (IBNR) claims in actuarial sciences. In this paper, we propose a copula-baseddependency model to capture the relationship between two main IBNR reserve variables,i.e., the \time between two successive occurrences" and \delay time".A maximumlikelihood estimation method is used to estimate the parameters of the model. A simulationstudy is conducted to evaluate the validity of the theoretical results. Moreover, the proposedmethod is applied to predict the number of claims for the next years of a portfolio froma major automobile insurer and is compared to the classical Chain-Ladder (CL) modelforecasting.
