This web page contains links to individual pages for each chapter in the book.    The web page for each chapter contains links to some or all of the following:

Some of the MATLAB analyses make use of a package developed by Jim Ramsay, available from a separate web site; click here for details.

Chapter 1: Introduction
General introduction to FDA with examples of the types of problem discussed later in the book.

Chapter 2: Life Course Data in Criminology
Turning discrete observations into functional data; regularization for estimating mean function from very noisy data; smoothed functional PCA; calculations involving basis expansions.

Chapter 3: The Nondurable Goods Index
Seasonal variation in a long time series; the phase-plane plot and its interpetation; plotting changes in seasonal variation using phase-plane plots.

Chapter 4: Bone Shapes from a Paleopathology Study
Characterizing functional data through landmarks; using functional PCA to pick out modes of variability; visualizing results of a functional PCA by plotting mean perturbed by components weight functions; varimax rotation of components; study of data by analysis of the individual PC scores.

Chapter 5: Modeling Reaction Time Distributions
Functional models for density functions; PCA of densities.

Chapter 6: Zooming in on Human Growth
Growth as a monotonic process; a differential equation for growth; phase and amplitude variation and the need for registration.

Chapter 7: Time Warping Handwriting and Weather Records
Two examples of registration; registering sample curves to their mean; registering a single long time series to its seasonal variation.

Chapter 8: How do Bone Shapes Indicate Arthritis?
Parametrizing shapes when there are no landmarks; PCA of vector functions; functional discriminant analysis and the necessity of regularization.

Chapter 9: Functional Models for Test Items
Using FDA in a latent trait model for binary data; the item response and log odds-ratio functions; PCA of items; assessing test fairness; arc length measure of ability

Chapter 10: Predicting Lip Acceleration from Electromyography
A feed-forward or historical linear model.

Chapter 11: The Dynamics of Handwriting Printed Characters
Use differential equation modeling on handwriting data. Use this to illustrate what d. e. models are at all. PDA. Classification using PDA.

Chapter 12: A Differential Equation for Juggling
A differential equation as a model for functional data; plotting the results.
