The Oxford handbook of functional data analysis by Frédéric Ferraty( Book )

"As technology progresses, we are able to handle larger and larger datasets. At the same time, monitoring devices such as electronic equipment and sensors (for registering images, temperature, etc.) have become more and more sophisticated. This high-tech revolution offers the opportunity to observe phenomena in an increasingly accurate way by producing statistical units sampled over a finer and finer grid, with the measurement points so close that the data can be considered as observations varying over a continuum. Such continuous (or functional) data may occur in biomechanics (e.g. human movements), chemometrics (e.g. spectrometric curves), econometrics (e.g. the stock market index), geophysics (e.g. spatio-temporal events such as El Nino or time series of satellite images), or medicine (electro-cardiograms/electro-encephalograms). It is well known that standard multivariate statistical analyses fail with functional data. However, the great potential for applications has encouraged new methodologies able to extract relevant information from functional datasets. This Handbook aims to present a state of the art exploration of this high-tech field, by gathering together most of major advances in this area. Leading international experts have contributed to this volume with each chapter giving the key original ideas and comprehensive bibliographical information. The main statistical topics (classification, inference, factor-based analysis, regression modelling, resampling methods, time series, random processes) are covered in the setting of functional data. The twin challenges of the subject are the practical issues of implementing new methodologies and the theoretical techniques needed to expand the mathematical foundations and toolbox. The volume therefore mixes practical, methodological and theoretical aspects of the subject, sometimes within the same chapter. As a consequence, this book should appeal to a wide audience of engineers, practitioners and graduate students, as well as academic researchers, not only in statistics and probability but also in the numerous related application areas"--

DIVERS AUTEURS ONT RECEMMENT PROPOSE DES TESTS PERMETTANT DE COMPARER DEUX POPULATIONS PAR L'INTERMEDIAIRE DE L'ETUDE SIMULTANEE DES MATRICES DE COVARIANCE DE MEMES CARACTERES QUANTITATIFS OBSERVES SUR DEUX GROUPES D'INDIVIDUS OU ENCORE PAR LE BIAIS DE LA MISE EN EVIDENCE DE FACTEURS COMMUNS DANS LES ANALYSES EN COMPOSANTES PRINCIPALES EFFECTUEES A PARTIR DE CHAQUE POPULATION. NOTRE TRAVAIL COMPORTE DEUX VOLETS. L'UN EST THEORIQUE. ON MONTRE, GRACE A LA NOTION D'ANALYSE CANONIQUE DE DEUX SOUS-ESPACES, QUE, D'UNE FACON GENERALE, TOUTE METHODE CLASSIQUE DE TYPE FACTORIEL PEUT ETRE UTILISEE, MEME SANS HYPOTHESE DE NORMALITE, POUR LA COMPARAISON DE DEUX POPULATIONS. DANS UN CAS PARTICULIER, ENGLOBANT NOTAMMENT LES RESULTATS CONNUS, ON PROPOSE UN TEST DE MISE EN EVIDENCE DE FACTEURS COMMUNS AUX DEUX POPULATIONS. LE SECOND VOLET EST PRATIQUE. POUR RENDRE OPERATIONNELLE ET COMMODE L'UTILISATION DES TESTS DE COMPARAISON DE MATRICES DE COVARIANCE, NOUS AVONS CONCU, EN LANGAGE GAUSS, UN LOGICIEL COMPAR (VERSION EVOLUEE DU LOGICIEL COMPCOV QUE NOUS AVONS PRECEDEMMENT ECRIT) QUI PERMET, DANS CETTE PERSPECTIVE, UN TRAITEMENT UNIFIE DES DONNEES. CETTE DERNIERE VERSION DU LOGICIEL EST ILLUSTREE PAR DES EXEMPLES REELS ORIGINAUX OU TIRES DE LA LITTERATURE
Etude spectrale des processus stationnaires multidimensionnels et analyse en composantes principales dans le domaine des fréquence by Emmanuel Nicolas Cabral( Book )

2 editions published in 2010 in French and held by 2 WorldCat member libraries worldwide

Multidimensional statistical methods knew in these last decades very important developments both for theoretical (particularly in operatorial statistics) and application fields, allowing functional data treatments. The frequency domain's field (and its important tool the Fourier transform) allows particularly to permit the treatment of random functions and particular stochastic processes (stationary for example). In the study of random phenomenons which can be modeled by a p-dimensional process (Xt)t epsilon T, where each X belongs to Cp, it should be interesting, in one hand, to control the spectral tools associated with (Xt)t epsilon T and, in other hand, to obtain, in view of clarification, a q-dimensional process (with q < p) which best summarizes as possible (Xt)t epsilon T in a certain sense. There exists methods which allow to summarize a p-dimensional stationary continuous random function, defined on T = Z, R, [-pi,pi[ or, more generally, on a locally compact Abélian group. They lean on a criterion strictly closed to stationarity and their implementation is the Principal Component Analysis (PCA) of random measure associated with (Xt)t epsilon T. This PCA, also called, PCA in the frequency domain of (Xt)t epsilon T, consists on the PCA of each spectral component of (Xt)t epsilon T. We can present our contributions in the following four points: At first, it is well known that any stationary process can be associated with various spectral tools such as the random measure, the spectral measure with projector values and a unitary operator. We carry out a synthetic work about tensor and convolution products of random and spectral measures. This investment allows to answer, in practice, to interpolation problems, to identification of a spatial process, or to inverse Fourier transform problem. Secondly, given a periodic stationary process, we are interested in the specificity of its spectral tools. We define a notion of quasi-periodicity and quantify the closeness between the associated random measures of a quasi-periodic process and its periodic version. We study then the proximity between the corresponding PCA's in the frequency domain
