本人也在学习时间序列和用SAS程序实现,看到网上有很多人在问一些细节问题却鲜有回应,现找到一个详细介绍用SAS实现ARIMA模型的文件,分享一下!
格式:PDF
大小:109页
部分目录:
the three stages of ARIMA modeling
identification stage
estimate and diagnostic checking stage
forecasting stage
using ARIMA procedure statements
general notation for ARIMA models
stationary
differencing
subset, seasonal, and factored ARMA model
input variable and regression with ARMA errors
intervention models and interrupted time series
rational transfer function and distributed lag models
forecasting with input variables
data requirements

对每一步都解释得非常详细,而且对SAS程序的选项和表示的意义也说得很好,我觉得要用SAS来实现ARIMA的各种模型,这个材料都是足够的,呵呵:)
