Markov chain Monte Carlo (MCMC) algorithms offer a very general approach for sampling from arbitrary distributions. However, designing and tuning MCMC algorithms for each new distribution, can be challenging and time consuming. It is particularly dif

Slice sampling provides an easily implemented method for constructing a Markov chain Monte Carlo (MCMC) algorithm. However, slice sampling has two major drawbacks: (i) it requires repeated evaluation of likelihoods for each update, which can make it

We present a multivariate sufficient statistic using Kronecker products that dramatically increases computational efficiency in evaluating likelihood functions and/or posterior distributions. In particular, we examine the example of multivariate regr

Privacy-preserving data mining (PPDM) techniques aim to construct efficient data mining algorithms while main- taining privacy. Statistical disclosure limitation (SDL) tech- niques aim to preserve confidentiality but in contrast to PPDM techniques al

Factor analysis, classification and regression tree analysis (CART), discriminant analysis and classification analysis were applied to study land cover in Wyoming, to explore: 1) how environmental variables are related to one another; 2) whether land

A full Monte Carlo simulation of sample scattering and the final flight path for direct geometry time-of-flight spectrometers has been developed. This allows the scattering from systems with both realistic and complex scattering geometries as well as
