Stochastic processBroader topic: It is the discrete-time, discrete-state Markov case.
Exponential distributionRelated: Exponential holding times underpin continuous-time Markov chains.
Square matrixRelated: Transition probabilities among a finite set of states form a square matrix.
Path graphRelated: A random walk on a path graph gives a Markov chain with neighboring transitions.
Gambler’s ruinNarrower topic: Fortune levels form a finite Markov chain with two absorbing states.
Matrix theoryRelated: A transition matrix encodes its dynamics and long-run distributions.
