  2. Continuous-time Markov chain - Wikipedia

    en.wikipedia.org/wiki/Continuous-time_Markov_chain

    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 probabilities of a stochastic matrix. An equivalent formulation describes the process as changing state according to ...

  3. Markov chain - Wikipedia

    en.wikipedia.org/wiki/Markov_chain

    The continuous time Markov chain is characterized by the transition rates, the derivatives with respect to time of the transition probabilities between states i and j. Let X t {\displaystyle X_{t}} be the random variable describing the state of the process at time t , and assume the process is in a state i at time t .

  4. Markov renewal process - Wikipedia

    en.wikipedia.org/wiki/Markov_renewal_process

    A semi-Markov process (defined in the above bullet point) in which all the holding times are exponentially distributed is called a continuous-time Markov chain. In other words, if the inter-arrival times are exponentially distributed and if the waiting time in a state and the next state reached are independent, we have a continuous-time Markov ...

  5. Markovian arrival process - Wikipedia

    en.wikipedia.org/wiki/Markovian_arrival_process

    The Markov-modulated Poisson process or MMPP where m Poisson processes are switched between by an underlying continuous-time Markov chain. [8] If each of the m Poisson processes has rate λ i and the modulating continuous-time Markov has m × m transition rate matrix R, then the MAP representation is

    According to the figure, a bull week is followed by another bull week 90% of the time, a bear week 7.5% of the time, and a stagnant week the other 2.5% of the time. Labeling the state space {1 = bull, 2 = bear, 3 = stagnant} the transition matrix for this example is

  7. Kolmogorov's criterion - Wikipedia

    en.wikipedia.org/wiki/Kolmogorov's_criterion

    Consider this figure depicting a section of a Markov chain with states i, j, k and l and the corresponding transition probabilities. Here Kolmogorov's criterion implies that the product of probabilities when traversing through any closed loop must be equal, so the product around the loop i to j to l to k returning to i must be equal to the loop the other way round,

    So look, I think this is a real testament to the value of business and the importance of business being an example of how continuous learning and renewal plays out.

  9. Markov decision process - Wikipedia

    en.wikipedia.org/wiki/Markov_decision_process

    However, for continuous-time Markov decision processes, decisions can be made at any time the decision maker chooses. In comparison to discrete-time Markov decision processes, continuous-time Markov decision processes can better model the decision-making process for a system that has continuous dynamics , i.e., the system dynamics is defined by ...
