Embedded jump chain
Embedded Markov chain. One method of finding the stationary probability distribution, π, of an ergodic continuous-time Markov chain, Q, is by first finding its embedded Markov chain (EMC). Strictly speaking, the EMC is a regular discrete-time Markov chain. See more A continuous-time Markov chain (CTMC) is a continuous stochastic process in which, for each state, the process will change state according to an exponential random variable and then move to a different state as specified by the … See more Communicating classes Communicating classes, transience, recurrence and positive and null recurrence are … See more • Kolmogorov equations (Markov jump process) See more Let $${\displaystyle (\Omega ,{\cal {A}},\Pr )}$$ be a probability space, let $${\displaystyle S}$$ be a countable nonempty set, and let $${\displaystyle T=\mathbb {R} _{\geq 0}}$$ ($${\displaystyle T}$$ for "time").

My professor showed several ways to solve problems similar to these but I am on with this one. I have tried put the matrix into canonical form and using that to solve for the Q matrix, but I am running into issues ...

WebThe jump chain is very boring: it starts from 0 and moves with certainty to 1, then with certainty to 2, then to 3, and so on. 17.3 A brief note on explosion There is one point we have to be a little careful about with when dealing with continuous time processes with an infinite state space – the potential of “explosion”. WebApr 23, 2024 · The jump chain Y is formed by sampling X at the transition times (until the chain is sucked into an absorbing state, if that happens). That is, with M = sup {n: τn < …
WebNov 29, 2016 · In particular, for any t ≥ 0 , Xt = ik if tk ≤ t < tk + 1 Moreover, the distributions of the jump times and embedded chain are given by P(tk + 1 − tk ∣ Xtk = i) = Exp(qi), and P(ik + 1 = j ∣ Xtk = i) = qij qi. This representation is quite standard and shows that the process {Xt} is a càdlàg Markov jump process.

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.
