The text-book image of a Markov chain has a flea hopping about at random on the vertices of the transition diagram, Web25 okt. 2015 · As Lucia pointed out in a comment, by solving the hitting probability recursions for the Markov chain, you get that the distribution of the maximum is geometric; for k = 0, 1, 2, … , P ( M = k) = ( p 1 − p) k ( 1 − p 1 − p), or equivalently. P ( M ≥ k) = ( p 1 − p) k. There's actually a simple intuition for why the answer must be ...

WebAs seen in Figure 1 b, we found inspiration for generating heterogeneous multiple Markov chains with transition traits within a network sampling from the HMC. This inspiration alleviates random-walk behaviors while extracting samples by creating various heterogeneous chain paths on the target space of a network.

For each pair xand y of states, there is a probability p xy of going from state xto state ywhere for each x, P y p xy = 1. A random walk in the Markov chain consists of a sequence of states starting at some state x 0. In state x, the next state yis selected randomly with probability p xy. The starting
