问如何从GAM fits in R中提取和修改单个p.table组件EN我使用for循环在R中运行了一系列GAMs，这些GAMs...
extract_gam_coefficients<-function(gam_model){return(summary(gam_model)$p.coeff)} 1. 2. 3. 这个函数首先调用了summary函数从gam模型对象中提取系数。 以下是其他语言处理此逻辑的示例: # Bash 脚本示例Rscript-e'model <- gam(y ~ s(x1) + s(x2), data = my_data); coeffs <- summary(model...

I used ts (time series) function in R to complete the year fraction of each month in the dataset, other data manipulations can be found in my code. Then I used a generalized additive model to fit a model for the trends of the temperature. Generalized additive model is a method that des...
