In recent years, significant progress has been made in statistical theory. New methodologies have emerged, as an attempt to bridge the gap between theoretical and applied approaches. This volume presents some of these developments, which already have had a significant impact on modeling, design and analysis of statistical experiments. The chapters cover a wide range of topics of current interest in applied, as well as theoretical statistics and probability. They include some aspects of the design of experiments in which there are current developments - regression methods, decision theory, non-parametric theory, simulation and computational statistics, time series, reliability and queueing networks. Also included are chapters on some aspects of probability theory, which, apart from their intrinsic mathematical interest, have significant applications in statistics. This book should be of interest to researchers in statistics and probability and statisticians in industry, agriculture, engineering, medical sciences and other fields.
