WebOct 24, 2016 · I have an inclination, unfortunately with no proof, that the stationary distribution of a Continuous Time Markov Chain and its embedded Discrete Time Markov Chain should be if not the same very similar. Discrete Time Markov chains operate under the unit steps whereas CTMC operate with rates of time. WebDec 24, 2016 · Here we introduce a hybrid Markov chain epidemic model, which maintains the stochastic and discrete dynamics of the Markov chain in regions of the state space where they are of most importance, and uses an approximate model—namely a deterministic or a diffusion model—in the remainder of the state space.

WebIn this section, we sill study the Markov chain $ \bs{X} $ in terms of the transition matrices in continuous time and a fundamentally important matrix known as the generator. Naturally, the connections between the two points of view are particularly interesting. The Transition Semigroup Definition and basic Properties Embedded Markov chain.
