L’ouvrage commence par présenter les graphiques pour séries temporelles offerts par R sur quelques séries. Il fournit ensuite des rappels de statistique mathématique et révise les concepts et les modèles classiques de séries. Il présente les structures de séries temporelles dans R et l’importation de telles séries. Il revisite le lissage exponentiel, à la lumière des travaux des 20 dernières années sur la question. Un chapitre est consacré à la simulation de séries. Les méthodes sont rapidement illustrées à l’aide de séries le plus souvent simulées. On étudie ensuite en détail six séries, avec, le plus souvent, la confrontation de plusieurs approches.

This book is a self-teaching guide to the SPSS for Windows computer package. It is designed to be used with SPSS version 8.0 and beyond, although many of the procedures are also applicable to earlier versions of SPSS. This guide is ex tremely easy to follow since all procedures are outlined in a straightforward, step-by-step format. Because of its self-instructional nature, the beginning stu dent can learn to analyze statistical data with SPSS without outside assistance. The reader is "walked through" numerous examples that illustrate how to use the SPSS package. The results produced by SPSS are shown and discussed in each application. Each chapter demonstrates statistical procedures and provides exer cises that reinforce the text examples and can be performed for further practice. Chapter 1 of this guide describes how to start the SPSS program and how to open data files. Chapters 2 through 16 give descriptions of statistical procedures which assume that a data file has been opened. This manual describes basic de scriptive statistics through multiple regression analysis, with three chapters (7-9) that discuss probability theory. Simple definitions of statistical concepts are pro vided for each procedure.
