  • Chapter 8 GAM validation | Workshop 8: Generalized additive models in R - QCBS
    So, what can we do if the observations of the response variable do not follow a Normal distribution? Or if the variance is not constant (heteroscedasticity)? Just like generalized linear models (GLM), we can formulate generalized additive models to deal with these issues
  • GAM(广义可加模型)，R语言mgcv详解（1）保姆级教程
    GAM 是最常用的一种描述变量间非线性关系的模型，常用于分析生物与环境之间的关系， 其一般表达式为： 式中，𝑔()为连接函数，𝑓𝑖 为解释变量的平滑函数，𝑌为响应变量，𝑥𝑖 为解释变量， 𝛼截距项，n 为解释变量的数量，ε为残差。
  • Checking, Selecting Predicting with GAMs - School of Mathematics
    Since a GAM is just a penalized GLM, residual plots should be checked, exactly as for a GLM The distribution of scaled residuals should be examined, marginally, and plotted against covariates and fitted values residuals(model) extracts residuals gam check(model) produces simple residual plots, and summary ̧ estimation convergence information
  • Producing insights with Generalized Additive Models GAMs
    GAMs is a versatile framework that can be applied to almost any field In our context, we could create a model that explains how the number of rented bikes changes due to the flexible behavior of time, humidity, and temperature Additionally, the number of rented bikes behaves like a Normal distribution We can write our model formally as:
  • 非线性模型之广义相加模型(GAM)-原理与应用概述 - 知乎
    GAM让我们可以灵活地对非线性关系进行建模。 Generalized 广义是指预测变量与因变量之间的关系可以是非线性的，并且可以通过非参数光滑函数来建模。
