In analysing time series of counts, the need to test for the presence of a dependence structure routinely arises. Suitable tests for this purpose are considered in this paper.

This article considers goodness-of-fit tests for bivariate INAR and bivariate Poisson autoregression models. The test statistics are based on an L2-type distance between two estimators of the probability generating function of the observations: one being entirely nonparametric and the second one...

This paper investigates whether a "Golden Rule" of regulation of an infectious disease may be elicited that balances the economic control and disease costs when the arrival of a future vaccine or a cure is uncertain. Formulating an optimal control problem applied to standard compartment models...
