"This book will be a good reference book in the area of longitudinal data. It provides a self-contained treatment of structured nonparametric models for longitudinal data. Three commonly used method-kernel, polynomial splines, penalization/smoothing splines are all treated with enough depth. The book's coverage of time-varying coefficient models is comprehensive. Shared-parameter and mixed-effects models are very useful in longitudinal data analysis. Section V 'Nonparametric Models for Distribution' summarizes recent development on a new class of models. This section alone will make the book unique among all published books in longitudinal data analysis. Another unique feature of the book is the use of four actual longitudinal studies presented in Section 1.2. The book used data from these four studies when introducing every model/method. This approach motivates each method very well and also shows the usefulness of the method...The book will be an excellent addition to the literature." ~Jianhua Huang, Texas A&M University". . . , this book provides a comprehensive review of the structure of longitudinal data, as well as several applicable nonparametric models. It should prove useful for those working with biomedical data, including real world evidence. The focus is on theorems and proofs; references demonstrate the depth of the research. Real life examples are provided in the form of data descriptions, as well as R code and output. These examples will allow the reader to employ the models and gain expertise in the interpretation of the R output."~Journal of Biopharmaceutical Statistics, Darcy Hille, Merck Research Laboratories"The authors are to be commended for such a thorough and well written book, which would certainly be of interest to anyone involved in analysing complex longitudinal data or with an interest in nonparametric approaches."~David Hughes, ISCB Newsletter
