โœฆ Synopsis

The paper reviews and generalizes recent filtering and smoothing algorithms for observations generated by a state model. In particular the paper discusses the modified Kalman filter derived by Ansley and Kohn (1985) and Kohn and Ansley (1986) to deal with state space models having partially diffuse initial conditions, and shows how to compute the limiting normalized likelihood of the observations for such models. The paper also discusses and generalizes the new smoothing algorithm presented by Kohn and Ansley (1987c, 1989) and extends it to state space models with partially diffuse initial conditions.

In this paper, fast algorithms are suggested for the optimal FIR filter and smoother of discrete-time state-space models with system noise. While the computation order of the previous algorithms for the optimal FIR filter and smoother is O(N 2) with filter length N, it is shown in this paper that it

Three general classes of state space models are presented, using the single source of error formulation. The first class is the standard linear model with homoscedastic errors, the second retains the linear structure but incorporates a dynamic form of heteroscedasticity, and the third allows for non

Stochastic volatility models (SVMs) represent an important framework for the analysis of financial time series data, together with ARCH-type models; but unlike the latter, the former, at least from the statistical point of view, cannot rely on the possibility of obtaining exact inference, in particu
