Irreducibility what the starting point. Although the initial results are relatively simple, the impact of an appropriate irreducibility structure will have wide-ranging consequences, and it is therefore of critical importance that such structures be well understood.

Topology and Continuityhe context we shall most frequently use is also a probabilistic one: in Part II, stability properties such as recurrence or regularity will be defined as certain return to sets of positive ψ-measure, or as finite mean return times to petite sets, and so forth.

The Nonlinear State Space Modelail, albeit rather general and multidimensional ones. This chapter is intended as a relatively complete description of the way in which nonlinear models may be analyzed within the Markovian context developed thus far. We will consider both the general nonlinear state space model, and some specific a

Drift and Regularityes a fundamental stability requirement of many classes of models. Indeed, in time series analysis for example, a standard starting point, rather than an end-point, is the requirement that the model be stationary, and it follows from (10.4) that for a stationary version of a model to exist we are in

叫喊

Geometric Ergodicity only π(ƒ) < ∞. Strong though this is, for many models used in practice even more can be said: there is often a rate of convergence ρ such that.where the rate ρ < 1 can be chosen essentially independent of the initial point ..

歪曲道理

-Uniform Ergodicityrgence of an operator norm; simultaneously, we show that the classical concept of uniform (or strong) ergodicity, where the convergence in (13.4) is bounded independently of the starting point, becomes a special case of this operator norm convergence.
