These methods are called "generalized additive models". For example, a commonly used statistical model in medical research is the logistic regression model for binary data. Here we relate the mean of the binary response = P (y = 1) to the predictors via a linear regression model and the ...
Generalized Additive Models (GAM),或者广义可加模型,是统计学中一种常用的非参数回归方法。它结合了广义线性模型(GLM)和非线性平滑方法,能够适应非线性、非正态分布和非常数方差的数据。本文将详细介绍GAM算法,并一步一步回答与其相关的问题。 第一部分:GAM算法的介绍 1.1什么是广义可加模型? 广义可加模型是一种...
推荐 内容简介· ··· This book describes an array of power tools for data analysis that are based on nonparametric regression and smoothing techniques. These methods relax the linear assumption of many standard models and allow analysts to uncover structure in the data that might otherwise have ...

which will be focused on. Generalized Additive Models 2 In both packages, actually more general models can be fit. As mentioned, interactions can be added with the use of thin-plate splines. In addition, the semiparametric model can be fit. It has the form E[Y |X, Z 1 , . . ...
An Introduction to Generalized Additive Models with R provides readers with a thorough understanding of the theory and practical applications of GAMs to enable informed use of these very flexible tools and other advanced related models. The author's approach is based on a framework of penalized regr...

(The predictor remains linear in the parameters, of course; nonlinear models are nonlinear in their parameters and are the subject of Chapter 14.) In this chapter, however, we consider some more flexible models in which the relationship between the response variable and one or more of the ...
