GAMM是一种灵活而强大的统计建模方法,它结合了广义可加模型(Generalized Additive Model, GAM)和混合效应模型(Mixed Effects Model)。通过引入非线性平滑函数和随机效应,GAMM能够更准确地描述变量之间的复杂关系,并考虑到数据中可能存在的随机变异。 本文将详细介绍GAMM的理论基础、模型框架和参数估计方法。同时,我们还将...

To overcome these difficulties, Hastie and Tibshirani (1990) proposed generalized additive models (GAMs). GAMs are ...
A generalized additive mixed model has the form g(µ i ) = A i θ+ j L ij f j (x j )+Zb, b ∼ N(0, ψ), y i ∼ EF(µ i ,φ) . . . actually this is not much different to a GAM. The random effects term Zb is just like a smooth with penalty b T ψ...

An additive mixed model as we employ here can be written as yit = α+ x1itβ1 + …+xkitβk + s1(x(k+ 1)it)+s2(x(k+ 2)it)+…+vit for i = 1,…,21 locations, t = 1951,… ,2005 and v ∼ N(0,σ2Λ). s() means that the term is estimated nonparametrically. Many ...
