COMPSTAT

This volume contains six invited papers, 41 contributed papers and two papers which are, formally, software descriptions, but it was agreed by the Program Committee that they should be included in a separate section entitled "Notes About New Developments in Statistical Software", due to their special significance for current trends in computational statistics. All contributions are grouped into ten topics: "Classification; "Algorithms and Statistical Software"; "Expert Systems in Statistics"; "Multivariate Data Analysis and Model Building"; "Optimization Techniques and Non-linear Models"; "Computing for Robust Statistics"; "Statistics and Database Management"; Time-Dependent Models analysis of Spatial Data"; and "Computational Inference". The structure and content of these papers are a good indicator of the current interests in computational statistics. As in past years, this 9th COMPSTAT is dominated by multivariate data analysis, expert systems in statistics and algorithms, and statistical software.
