Recent Advances in Functional Data Analysis and Related Topics -

Résumé :
New technologies allow us to handle increasingly large datasets, while monitoring devices are becoming ever more sophisticated. This high-tech progress produces statistical units sampled over finer and finer grids. As the measurement points become closer, the data can be considered as observations varying over a continuum. This intrinsic continuous data (called functional data) can be found in various fields of science, including biomechanics, chemometrics, econometrics, environmetrics, geophysics, medicine, etc. The failure of standard multivariate statistics to analyze such functional data has led the statistical community to develop appropriate statistical methodologies, called Functional Data Analysis (FDA). Today, FDA is certainly one of the most motivating and popular statistical topics due to its impact on crucial societal issues (health, environment, etc). This is why the FDA statistical community is rapidly growing, as are the statistical developments . Therefore, it is necessary to organize regular meetings in order to provide a state-of-art review of the recent advances in this fascinating area. This book collects selected and extended papers presented at ?the second International Workshop of Functional and Operatorial Statistics (Santander, Spain, 16-18 June, 2011), in which many outstanding experts on FDA will present the most relevant advances in this pioneering statistical area. Undoubtedly, these proceedings will be an essential resource for academic researchers, master students, engineers, and practitioners not only in statistics but also in numerous related fields of application. ?

Critique:
From the reviews: Topics are useful, interesting, and related to the hot area of high-dimensional data analysis. I think the volume will draw attention from researchers as well as practitioners involved in the areas of functional data, high-dimensional data and spatial functional data, and related topics. ... The style and structure of the book is unified, and some chapters are more theoretical than others. Again, it is a collection of wide and diverse topics. ... graduate students and researchers in this area will find this book useful. (Technometrics, Vol. 54 (1), February, 2012)
