Importance Sampling - U-M LSA

This method is only considered reliable when the weights are not too variable. As a rule of thumb, when ESS = v u u t1 N XN i=1 w˜(X i) w −1 2 is less than 5, this method is reasonable. Here w is the sample mean of the ˜w(X i)’s. You will know you’ve chosen a bad g is ESS is large. When ESS < 5, the variance of E(h(X)) IS can be ...

Chapter 1 Markov Chains - Yale University

2 1MarkovChains 1.1 Introduction This section introduces Markov chains and describes a few examples. A discrete-time stochastic process {X n: n ≥ 0} on a countable set S is a collection of S-valued random variables defined on a probability space (Ω,F,P).The Pis a probability measure on a family of events F (a σ-field) in an event-space Ω.1 The set Sis the state space of the …
