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. Webb1.4 Nice properties for Markov chains Let’s de ne some properties for nite Markov chains. Aside from the \stochastic" property, there exist Markov chains without these properties.

WebbA Markov chain is a random process with the Markov property. A random process or often called stochastic property is a mathematical object defined as a collection of random variables. A Markov chain has either discrete state space (set of possible values of the random variables) or discrete index set (often representing time) - given the fact ...

Before reading this lecture, you should review the basics of Markov chains and MCMC.

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.

In a simple random walk, the location can only jump to neighboring sites of the lattice, forming a lattice path.
