STATIONARY AND NON‐STATIONARY STATE SPACE MODELS

Journal of Time Series Analysis, 1994
Abstract. The concepts of time invariance, stationarity, non‐stationarity and immemorial time are considered for state space models (SSMs). Necessary and sufficient conditions for stationarity are given and connected with standard conditions. Expressions are given for the unconditional mean and covariance matrix of the state of a time‐immemorial SSM ...

Learning and imprinting in stationary and non-stationary environment

Kybernetik, 1973
The performance of the extended Bush-Mosteller learning and imprinting scheme developed previously is studied for stationary and non-stationary stochastic environments. As a performance criterion the average missing information level is chosen. For a stationary environment the approximate time course of the latter is derived and discussed, an exact ...

Stationary Cardinals

Archive for Mathematical Logic, 1993
Let \(\kappa\) be an uncountable cardinal. A subset \(A\subseteq \kappa\) is said to be a 1-club set if \(A\) is stationary and every stationary reflection point belongs to \(A\). It is clear that this definition is a generalization of the definition of closed unbounded sets.
