Random walk on Markov Chain Transition matrix - Stack Overflow

Webb2,··· is a Markov chain with state space Zm. It is called the general random walk on Zm. If m = 1 and the random variable Y (i.e. any of the Y j’s) takes only values ±1 then it is called a simple random walk on Z and if in addition the values ±1 are assumed with equal probability 1 2 then it is called the simple symmetric random walk on Z. WebbFor this paper, the random walks being considered are Markov chains. A Markov chain is any system that observes the Markov property, which means that the conditional probability of being in a future state, given all past states, is dependent only on the present state.
