S+Functional Data Analysis is the first commercial object oriented package for exploring, modeling, and analyzing functional data. Functional data analysis (FDA) handles longitudinal data and treats each observation as a function of time (or other variable). The functions are related. The goal is to analyze a sample of functions instead of a sample of related points. FDA differs from traditional data analytic techniques in a number of ways. Functions can be evaluated at any point in their domain. Derivatives and integrals, which may provide better information (e.g. graphical) than the original data, are easily computed and used in multivariate and other functional analytic methods.The analyst using S+FDA can handle irregularly spaced data or data with missing values. For large amounts of data, working with a functional representation can save storage. Moreover, S+FDA provides a variety of analytic techniques for functional data including linear models, generalized linear models, principal components, canonical correlation, principal differential analysis, and clustering.This book can be considered a companion to two other highly acclaimed books involving James Ramsay and Bernard Silverman: Functional Data Analysis, Second Edition (2005) and Applied Functional Data Analysis (2002).This user's manual also provides the documentation for the S+FDA library for SPlus.

Scientists and others today often collect samples of curves and other functional observations. This monograph presents many ideas and techniques for such data. Included are expressions in the functional domain of such classics as linear regression, principal components analysis, linear modeling, and canonical correlation analysis, as well as specifically functional techniques such as curve registration and principal differential analysis. Data arising in real applications are used throughout for both motivation and illustration, showing how functional approaches allow us to see new things, especially by exploiting the smoothness of the processes generating the data. The data sets exemplify the wide scope of functional data analysis; they are drawn from growth analysis, meteorology, biomechanics, equine science, economics, and medicine.The book presents novel statistical technology, much of it based on the authors? own research work, while keeping the mathematical level widely accessible. It is designed to appeal to students, to applied data analysts, and to experienced researchers; it will have value both within statistics and across a broad spectrum of other fields.This second edition is aimed at a wider range of readers, and especially those who would like to apply these techniques to their research problems. It complements the authors' other recent volume Applied Functional Data Analysis: Methods and Case Studies. In particular, there is an extended coverage of data smoothing and other matters arising in the preliminaries to a functional data analysis. The chapters on the functional linear model and modeling of the dynamics of systems through the use of differential equations and principal differential analysis have been completely rewritten and extended to include new developments. Other chapters have been revised substantially, often to give more weight to examples and practical considerations.

Scientists often collect samples of curves and other functional observations, and develop models where parameters are also functions. This volume in the UseR! Series is aimed at a wide range of readers, and especially those who would like apply these techniques to their research problems. It complements Functional Data Analysis, Second Edition and Applied Functional Data Analysis: Methods and Case Studies by providing computer code in both the R and Matlab languages for a set of data analyses that showcase functional data analysis techniques. The authors make it easy to get up and running in new applications by adapting the code for the examples, and by being able to access the details of key functions within these pages. This book is accompanied by additional web-based support at http://www.functionaldata.org for applying existing functions and developing new ones in either language. The companion 'fda' package for R includes script files to reproduce nearly all the examples in the book including all but one of the 76 figures.

Most of us, most of the time, prefer not to think about the universal experience of death. Death arouses disturbing instincts, emotions and memories. This is a book for those wishing to understand more about the Christian journey at the end of life, but it is not just a book about death, it is also about living with courage and grace and about facing our fears. The author writes both for the dying and for those who accompany them. He examines the questions that we are often too afraid to ask, and helps us to encompass death through a deeper understanding of the promise of union with God and life everlasting.

Sugar cane plantations had operated across almost every island in the West Indies since the seventeenth century. Run by British planters, they relied on slavery as their main source of labour. A surgeon and Anglican minister, James Ramsay (1733-89) witnessed at first hand the exploitation of African slaves in Britain's West Indian colonies. Working there for over twenty years, as both a Christian missionary and a practising surgeon, he became keenly involved in the campaign to improve the welfare of slaves. This extended essay, first published in 1784, was an early and highly influential contribution to the anti-slavery movement, generating both enlightened acclaim and deep opposition. Analysing the relationships between slaves and their masters, discussing the role of slaves in society, and proposing various measures to improve their lives, this work remains a relevant text in Caribbean and colonial history.

This text focuses on the use of smoothing methods for developing and estimating differential equations following recent developments in functional data analysis and building on techniques described in Ramsay and Silverman (2005) Functional Data Analysis. The central concept of a dynamical system as a buffer that translates sudden changes in input into smooth controlled output responses has led to applications of previously analyzed data, opening up entirely new opportunities for dynamical systems. The technical level has been kept low so that those with little or no exposure to differential equations as modeling objects can be brought into this data analysis landscape. There are already many texts on the mathematical properties of ordinary differential equations, or dynamic models, and there is a large literature distributed over many fields on models for real world processes consisting of differential equations. However, a researcher interested in fitting such a model to data, or a statistician interested in the properties of differential equations estimated from data will find rather less to work with. This book fills that gap.

Security threats today are increasingly complex, dynamic, and asymmetric, and can affect environmental factors like energy, water, and food supply. As a result, it is becoming evident that the traditional model of nation-state based security is incomplete, and that purely military capabilities, though necessary, are insufficient to protect the United States and other democracies from the array of threats that challenge liberty and the free flow of people and commerce. A more complete picture of modern national security requires a more complete integration of the question of environmental security.The purpose of text is to better address the many aspects of environmental security and to represent this major area of academic research in an introductory text format that can be used in the rapidly growing number of homeland security studies programs as well as related degree programs. The concepts, challenges, and case studies in this text vitally extended such curricula, giving students a deeper appreciation for the critical role environmental security plays in overall state security, as well as for our nation, our way of life, and indeed for the human race at large.
