Summary

Traditionally, statistical analysis is divided into two stages: an exploratory stage, based on a comprehensive process of descriptive and graphic techniques; and a decision stage, based on probabilistic models. The exploratory phase, also called data analysis - and which is the object of this book - is the process of transforming data and extracting useful information. This process is normally composed of detailed and often complex exploratory methods that apply to multidimensional data and often exceed the capacity of the exploratory framework itself.

Author Biography

Grard Govaert is Professor at the University of Technology of Compigne, France. He is also a member of the CNRS Laboratory Heudiasyc (Heuristics and diagnostics of complex systems). His research interests include latent structure modeling, model selection, model-based cluster analysis, block clustering and statistical pattern recognition.
