Filtering out short-term fluctuations in the estimation of long-term smooth trends using temporal random effects in a generalized additive mixed model provides more robust inference about the long-term trends c
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...

be more appropriate. In the present study, observations were collected from the same individuals over time. It is reasonable to assume that correlations exist among the observations from the same individual, so we utilized generalized additive mixed models (GAMM) to investigate the effects of ...

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 ...

In Section 4, we have illustrated and explained all separate parts of an appropriate generalized additive modeling analysis. Now we are ready to create an appropriate model for all data (dataset full), including the appropriate random-effects structure and a correction for autocorrelation. An importa...
