Multiple Factor Analysis by Example Using R (Hardcover): Jerome Pages Multiple Factor Analysis by Example Using R (Hardcover)

Multiple factor analysis (MFA) enables users to analyze tables of individuals and variables in which the variables are structured into quantitative, qualitative, or mixed groups. Written by the co-developer of this methodology, Multiple Factor Analysis by Example Using R brings together the theoretical and methodological aspects of MFA. It also includes examples of applications and details of how to implement MFA using an R package (FactoMineR). The first two chapters cover the basic factorial analysis methods of principal component analysis (PCA) and multiple correspondence analysis (MCA). The next chapter discusses factor analysis for mixed data (FAMD), a little-known method for simultaneously analyzing quantitative and qualitative variables without group distinction. Focusing on MFA, subsequent chapters examine the key points of MFA in the context of quantitative variables as well as qualitative and mixed data. The author also compares MFA and Procrustes analysis and presents a natural extension of MFA: hierarchical MFA (HMFA). The final chapter explores several elements of matrix calculation and metric spaces used in the book.

Emergency Planning Guide for Utilities (Hardcover, 2nd edition): Francois Le, Jerome Pages, Samuel Mullen Emergency Planning Guide for Utilities (Hardcover, 2nd edition)

An increase in major natural disasters-and the growing number of damaging events involving gas, electric, water, and other utilities-has led to heightened concerns about utility operations and public safety. Due to today's complex, compliance-based environment, utility managers and planners often find it difficult to plan for the action needed to help ensure organization-wide resilience and meet consumer expectations during these incidents. Emergency Planning Guide for Utilities, Second Edition offers a working guide that presents new and field-tested approaches to plan development, training, exercising, and emergency program management. The book will help utility planners, trainers, and responders-as well as their vendors and suppliers-to more effectively prepare for damaging events and improve the level of the utility's resilience. It also focuses on planning needed in the National Incident Management System and ICS environment that many utilities are embracing going forward. In doing so, utilities will be able to improve the customer experience while reducing the impact that damaging events have on the utility's infrastructure, people, and resources.

Exploratory Multivariate Analysis by Example Using R (Hardcover, 2nd edition): Francois Husson, Sebastien  Le, Jerome Pages Exploratory Multivariate Analysis by Example Using R (Hardcover, 2nd edition)

Full of real-world case studies and practical advice, Exploratory Multivariate Analysis by Example Using R, Second Edition focuses on four fundamental methods of multivariate exploratory data analysis that are most suitable for applications. It covers principal component analysis (PCA) when variables are quantitative, correspondence analysis (CA) and multiple correspondence analysis (MCA) when variables are categorical, and hierarchical cluster analysis. The authors take a geometric point of view that provides a unified vision for exploring multivariate data tables. Within this framework, they present the principles, indicators, and ways of representing and visualising objects that are common to the exploratory methods. The authors show how to use categorical variables in a PCA context in which variables are quantitative, how to handle more than two categorical variables in a CA context in which there are originally two variables, and how to add quantitative variables in an MCA context in which variables are categorical. They also illustrate the methods using examples from various fields, with related R code accessible in the FactoMineR package developed by the authors.
