This is a clever didactical change because it makes the equivalence of smooth regression and random effect models much clearer. I found the 2nd edition of this book much more readable than the Generalized additive models are the go-to method for coping with non-linear relations between modeled outcomes and covariates -- this is a topic which should be a standard tool in statistical methodology. It meets the authors aim of providing a fairly full, but concise, theoretical treatment, explaining how the models and methods work. "Philip Reiss, University of Haifa and New York University, "This excellent and well-written book covers a lot more than "merely" GAMs, with the first few chapters providing a pretty comprehensive guide to regression modelling in general.

"Trevor Hastie, Stanford University, "The first edition of Simon Woods Generalized Additive Models appeared in 2006 to wide and well-deserved acclaim. ", A strength of this book is the presentation style . Something went wrong. ", "With this second edition, it may be safe to say that Simon Wood has made Generalized Additive Models (and its extensions) more accessible to researchers, practitioners, teachers, and students than ever before. and It is a good starting point for someone who wants an overview of these models in order to branch out into more advanced topics. Chapter 6 brings the smoothing/GAM presentation into contemporary and state-of-the-art light, for one by making the reader aware of relationships among P-splines, mixed models, and Bayesian approaches. The books title is a complete understatement. There is a new chapter on mixed effects models that expands on material in the first edition, more on GLMMs, an extended chapter on Smoothers that includes treatment of Gaussian Markov Random fields, and well-organised solutions to exercises.If you teach courses on linear models, GLMs, GLMMs, GAMs or GAMMs you will find this book a valuable resource for theoretical material, for illustrative applications, for exercises, and as a guide to using the mgcv package in your course. A generalized additive modeling (GAM) approach was used to model data collected from the field (with the package 'gamm4' in the statistical language R). These inferential developments are backed up by additional details on a large number of smooth terms and response distributions that significantly enhance the applicability of (extended) generalized additive models. Please try again. Item Width 6.3in. We are sorry. Clearly, Simon Wood is one of the driving forces of the success of generalized additive models both due to the software he provides and due to his in-depth theoretical investigation of the underlying properties. In addition to being my go-to text for generalized additive models, it provides a very clear and concise introduction to linear models, linear mixed models, generalized linear models and generalized additive mixed models. Reviewed in the United States on July 23, 2021. The way models are fit in practice may not be the best way to present them in theory, nor the best way for theoretical progress. Other models, such as neural networks, are quite flexible, but very difficult to interpret. Each chapter contains an extensive set of exercises, with solutions in an appendix or in the books R data package gamair, to enable use as a course text or for self-study. Prof Wood has a rare ability to see both the wood and the trees with incisive clarity."Prof. The generous use of graphs and plots helps visualization and enhances understanding. There are also many instances of discussion about these models from a Bayesian perspective and some examples of their implementation. I found the 2nd edition of this book much more readable than the 1st. GAMs through mgcv have changed my modeling life, and this book is a fantastic manual enabling that enough theory when I want to dig in deep to a particular facet, readable and including enough examples to help me spin up quickly for practical use, when I dont need the full technical details, and broad enough to capture my specialized use cases outside of whats typically presented in online tutorials. The response is assumed to be conditionally distributed according to some exponential family distribution (e.g., binomial, Poisson or Gamma distributions for trial, count or strictly positive real responses, respectively). Even though the author tries to be "practical", and gives some useful advice, the theory starts from really high level. Chapman and Hall/CRC. The tools and the theory covered by this book and its predecessor have certainly been a major influence on my own statistical practice over the last 20 years, and I have no doubt they will continue to be. : The books title is a complete understatement. Introduction | Generalized Additive Models Introduction Beyond the General Linear Model I General Linear Model Let's get started by considering the standard linear regression model (SLiM) estimated via ordinary least squares (OLS). Although closely related to the other two volumes, this Before starting below, you'll want to have a dataset that contains sampled values with associated predictor values. a much extended overview on methods to select the smoothing parameters, but also high level inference via hypothesis testing, p-values or an Akaike information criterion that takes smoothing parameter uncertainty into account. The author bases his approach on a framework of penalized regression splines, and while firmly focused on the practical aspects of GAMs, discussions include fairly full explanations of the theory underlying the methods. This book is definitely covering the state-of-the-art in modern smooth modelling. I strongly recommend this new edition due to all the reasons I have mentioned above.". In his newly revised text, Wood expertly and engagingly guides the reader from background material on linear and generalized linear models all the way through the latest developments in generalized additive (mixed) models. this is an excellent reference book for a broad audience Christine M. Anderson-Cook (Los Alamos National Laboratory), in, Journal of the American Statistical Association, "This is an amazing book.

The extensive examples using the mgcv R package are realistic and not over-simplified, and nicely show when enough work is enough. As the book includes many advanced topics and the necessary theory but develops everything from the basics, it will be of interest to statistical researchers and practitioners alike. I would recommend it to anyone interested in statistical modelling. Generalized Additive Models are very nice and effective way of fitting Linear Models which depends on some smooth and flexible Non-linear functions fitted on some predictors to capture Non-linear . One of my very first thoughts when looking at this book was just how lucky students are these days to have books like this one that carefully and intelligibly place such vast, powerful, and flexible modeling tools at their fingertips. Let's begin with its Implementation in R . , Chapman and Hall/CRC; 2nd edition (May 18, 2017), Publication date One of my very first thoughts when looking at this book was just how lucky students are these days to have books like this one that carefully and intelligibly place such vast, powerful, and flexible modeling tools at their fingertips. In the ten years since the publication of the first edition, not only the mgcv package, but also the underlying theory have made much progress and it is therefore good to see the second edition reflecting both developments and comprising a lot of new and fascinating material.

It is an extension package and contains the possible variation available with generalized additive models. 13.2 Generalized Additive Models In the development of generalized linear models, we use the link function g to relate the conditional mean (x) to the linear predictor (x). An alternative approach is provided by Generalized Addictive Models, which allows us to fit models with non-linear smoothers without specifying a particular shape a priori. The reader gains confidence, as if anything is possible, and the examples using software puts modern and sophisticated modeling at their fingertips. Generalized Additive Models for Location Scale and Shape. A generalized additive model (Hastie and Tibshirani, 1986, 1990) is a generalized linear model (GLM) with a linear predictor involving a sum of smooth functions of covariates. This leads to a coherent and extensible modelling framework throughout, which I would describe as broadly Bayesian but not dogmatically so. 2 - Interpreting and Visualizing GAMs His first edition had already "hit the nail on the head," but it is clear that this refined iteration was well-thought out and deliberately executed with sensitivity toward the reader. Show details Hide details. An extension to two popular approaches to modeling complex structures in ecological data: the generalized additive model (GAM) and the hierarchical model (HGLM), which allows modeling of nonlinear functional relationships between covariates and outcomes where the shape of the function itself varies between different grouping levels. Professor Brian D. Marx, Louisiana State University, USA, This attractively written advanced level text shows its style by starting with the question How old is the universe?. "Thomas Kneib, Georg-August-Universitt Gttingen, "With this second edition, it may be safe to say that Simon Wood has made Generalized Additive Models (and its extensions) more accessible to researchers, practitioners, teachers, and students than ever before.

There is a new chapter on mixed effects models that expands on material in the first edition, more on GLMMs, an extended chapter on Smoothers that includes treatment of Gaussian Markov Random fields, and well-organised solutions to exercises.If you teach courses on linear models, GLMs, GLMMs, GAMs or GAMMs you will find this book a valuable resource for theoretical material, for illustrative applications, for exercises, and as a guide to using the mgcv package in your course. This applies in particular to many novel elements on inference in generalized additive models, e.g. I was delighted to see the presentation of GAMs uses penalized splines - the author sorts through the clutter and presents a well-chosen toolbox. Overall, it provides a clear introduction, theory, and practical . Linear Models are considered the Swiss Army Knife of models. It is such a pleasure to see Simons broader approach toward extensions, e.g. Generalized additive models are the go-to method for coping with non-linear relations between modeled outcomes and covariates -- this is a topic which should be a standard tool in statistical methodology. Like his code, Simon writes his textbook in an uncompromising, sensible, and approachable way. I will not go into much details about the theory behind GAMs. Includes initial monthly payment and selected options. Clearly, Simon Wood is one of the driving forces of the success of generalized additive models both due to the software he provides and due to his in-depth theoretical investigation of the underlying properties. is a professor of Statistical Science at the University of Bristol, UK, and author of the R package mgcv. Case in point: an entire chapter is devoted to "GAMs in Practice." N. Wood's great book, "Generalized Additive Models: an Introduction in R" Some of the major development in GAMs has happened in the R front lately with the mgcv package by Simon N. Wood. , Up to 4 simultaneous devices, per publisher limits, Text-to-Speech The author has a style of hammering in a certain way of presenting the theory, when simpler approaches are out there. To calculate the overall star rating and percentage breakdown by star, we dont use a simple average. The author has a knack for writing in a round about way sometimes the first two chapters are, in my opinion, a bit awful. 360-361. f p ( x i p) + i. where the functions f 1, f 2, f 3, . Many further practical details are explained there.". The first edition of this book has established itself as one of the leading references on generalized additive models (GAMs), and the only book on the topic to be introductory in nature with a wealth of practical examples and software implementation.

If you do research that may require any of the above methods, you will find that this book provides an invaluable synthesis of the areas, as well as a reference source for the technical detail of the methods.I know of very few statistics books that combine such an accessible synthesis of a broad area of statistics with the rigor and detail that allows the reader to understand the intricacies of virtually any aspect of the area. Generalized Additive Models in R (2022) Generalized additivemodels in R GAMs in R are a nonparametric extension of GLMs, used oftenfor the case when you have no a priori reason for choosing a particularresponse function (such as linear, quadratic, etc.) There are good introductions of GAM itself needless to say the book written by the package developer (Wood, 2017) as well as well-summarised materials on the internet. For practitioners working with the R library mgcv, this second edition describes at length all the actual issues and possibilities of this powerful set of functions. In addition to being my go-to text for generalized additive models, it provides a very clear and concise introduction to linear models, linear mixed models, generalized linear models and generalized additive mixed models.
