On The Weak Law Of Large Numbers For Unbounded Functionals For Adaptive MCMC

چکیده

We present counter-examples to demonstrate that when g is unbounded the conditions of Simultaneous Uniform Ergodicity and Diminishing Adaptation are not enough to guarantee that the the weak law of large numbers (WLLN) holds, although from the results of Roberts and Rosenthal [4] we know that WLLN holds under these conditions when g is bounded. Then we show various theoretical results of the WLLN for the adaptive MCMC and unbounded measurable function g. Finally we apply our results to the Adaptive Metropolis algorithm proposed by Haario et al. [7] (2001).

Recurrent and Ergodic Properties of Adaptive MCMC

We will discuss the recurrence on the state space of the adaptive MCMC algorithm using some examples. We present the ergodicity properties of adaptive MCMC algorithms under the minimal recurrent assumptions, and show the Weak Law of Large Numbers under the same conditions. We will analyze the relationship between the recurrence on the product space of state space and parameter space and the erg...

SOME PROBABILISTIC INEQUALITIES FOR FUZZY RANDOM VARIABLES

In this paper, the concepts of positive dependence and linearlypositive quadrant dependence are introduced for fuzzy random variables. Also,an inequality is obtained for partial sums of linearly positive quadrant depen-dent fuzzy random variables. Moreover, a weak law of large numbers is estab-lished for linearly positive quadrant dependent fuzzy random variables. Weextend some well known inequ...

Coupling and Ergodicity of Adaptive MCMC

We consider basic ergodicity properties of adaptive MCMC algorithms under minimal assumptions, using coupling constructions. We prove convergence in distribution and a weak law of large numbers. We also give counter-examples to demonstrate that the assumptions we make are not redundant.

On the Convergence Rate of the Law of Large Numbers for Sums of Dependent Random Variables

In this paper, we generalize some results of Chandra and Goswami [4] for pairwise negatively dependent random variables (henceforth r.v.’s). Furthermore, we give Baum and Katz’s [1] type results on estimate for the rate of convergence in these laws.

A strong law of large numbers in credibility theory∗

In this paper, the issue of the law of large numbers for fuzzy variables is considered. Since in credibility theory convergence in credibility implies convergence almost sure, the strong law of large numbers is defined via convergence in credibility, while the weak law of large numbers is defined through convergence almost sure. Based on the convergence results about the unform integrability of...
