The standard Markov chain Monte Carlo method of estimating an expected value is to generate a Markov chain which converges to the target distribution and then compute correlated sample averages. In… (More)

interest and Ît,n = (1/n) ∑t+n−1 i=t f(Xi) its MCMC estimate. Precisely, we derive lower bounds for the length of the trajectory n and burn-in time t which ensure that P (|Ît,n − I| ≤ ε) ≥ 1− α. The… (More)

The Nummellin’s split chain construction allows to decompose a Markov chainMonte Carlo (MCMC) trajectory into i.i.d. “excursions”. RegenerativeMCMC algorithms based on this technique use a random… (More)

-The perceptron criterion function is used as a quality measure of linear discriminant function. A detailed description of an efficient algorithm of minimization of this criterion function is given.… (More)

MCMC methods are used in Bayesian statistics not only to sample from posterior distributions but also to estimate expectations. Underlying functions are most often defined on a continuous state space… (More)

An essential part of many problems encountered in Bayesian inference is the computation of analytically intractable integral I = πf = ∫ X f(x)π(x)dx, where f(x) is the target function of interest, X… (More)

In the thesis we take the split chain approach to analyzing Markov chains and use it to establish fixed-width results for estimators obtained via Markov chain Monte Carlo procedures (MCMC).… (More)

An algorithm for restoration of images degraded by Poisson noise is proposed. The algorithm belongs to the family of Markov chain Monte Carlo methods with auxiliary variables. We explicitly use the… (More)

Results of epidemiological and public health surveys are often presented in the form of cross-classification tables. It is sometimes difficult to analyze data described in this way and to understand… (More)
