Causality and Stochastic Dynamic Systems
Jelena B. Gill, Ljiljana Petrović · SIAM Journal on Applied Mathematics · 1987
This paper deals with the problem of determining the possible states of a stochastic dynamic system $S_1 $ with known outputs, provided it is in a certain causal relationship with another stochastic dynamic system $S_2 $ whose states (or some information about them) are given.
