This paper uses a copula model to identify the dependency structure for motor insurance data. The study identified the …. Furthermore, six(6) different copula models were fitted for the joint distribution of the claim frequency and severity. The gumbel … copula was observed to be the best copula model for accounting for the dependency structure between the claim frequency and …

computational efficiency and accuracy for computing marginal risk contributions of the popular Gaussian copula model and t-copula … parameters in the t-copula model. Extensive numerical tests on computing risk contributions were performed on various copula … importance sampling algorithms in computing risk measures and marginal risk contributions in copula credit models …
