WebTo show $S_n$ is a Markov chain, you need to show that $$P(S_n=x S_1,\ldots,S_{n-1})=P(S_n=x S_{n-1}).$$ In other words, to determine the transition probability to $S_n$, all you need is $S_{n-1}$ even if you are given the entire past. To do this, write $S_n=S_{n … WebJul 17, 2024 · To do this we use a row matrix called a state vector. The state vector is a row matrix that has only one row; it has one column for each state.

WebEvery Markov chain can be represented as a random walk on a weighted, directed graph. A weighted graph is one where each edge has a positive real number assigned to it, its “weight,” and the random walker chooses an edge from the set of available edges, in … WebIn our discussion of Markov chains, the emphasis is on the case where the matrix P l is independent of l which means that the law of the evolution of the system is time independent. For this reason one refers to such Markov chains as time homogeneous or having stationary transition probabilities. Unless stated to the contrary, all Markov chains
