6、aexp1;inputa1@@;year=intnx(‘year’,’1jan1742’d,_n_-1);formatyearyear4.;cards;输入太阳黑子数序列(见附表)run;3、保存此步骤中的程序，供以后分析使用（只需按工具条上的保存按钮然后填写完提问后就可以把这段程序保存下来即可）。4、绘数据与时间的关系图，初步识别序列，输入下列程序：procgplotdata=exp1;symboli=splinev=starh=2c=green;plota1*year;run;精彩文档实用标准文案2、提交程序，在graph

7、窗口中观察序列，可以看出此序列是均值平稳序列。3、识别模型，输入如下程序。procarimadata=exp1;identifyvar=a1nlag=24;run;4、提交程序，观察输出结果。初步识别序列为AR(3)模型。5、估计和诊断。输入如下程序：estimatep=3;run;6、提交程序，观察输出结果。假设通过了白噪声检验，且模型合理，则进行预测。7、进行预测，输入如下程序：forecastlead=6interval=yearid=yearout=out;run;procprintdata=out;run;8、提交程

8、序，观察输出结果。9、退出SAS系统，关闭计算机。实验二模拟AR模型一、实验目的：熟悉各种AR模型的样本自相关系数和偏相关系数的特点，为理论学习提供直观的印象。二、实验内容：随机模拟各种AR模型。三、实验要求：记录各AR模型的样本自相关系数和偏相关系数，观察各种序列图形，总结
