Recurrence and Ergodicity for Exponential Family State-Space Models
Abstract
We give two results concerning the properties of state-space models with exponential family observation distribution and conjugate state distribution. The first result gives a simple and general interpretation of the parameters of the predictive state distribution in terms of the observation forecast distribution. The second result shows how the first result can be used to check the long-term model properties of recurrence and ergodicity for a class of non-Gaussian observation distributions. In particular, these results apply to models with Poisson, binomial and multinomial observation distributions. Keywords: Bayesian forecasting; Binomial time series; Multinomial time series; Poisson time series; Recursive updating; Time series. (KR)
