It is well known that credibility theory in discrete time is closely related to the discrete technique of Kalman … filtering. In this paper we show the close relationship between credibility theory and filter theory in discrete and continuous … time as well as between credibility theory in a discrete and continuous time setting. …

In this paper we provide a unifed methodology in order to conduct likelihood-based inference on the unknown parameters of a general class of discrete-time stochastic volatility models, characterized by both a leverage effect and jumps in returns. Given the nonlinear/non-Gaussian state-space...
