Hello, I am working with Bowerman textbook Forecasting, Time Series, and Regression -4th edition. He presents many good examples but does not include all SAS code. My question has to do with proc arima and the SAS output from Bowerman. I am not getting the ACF and PACF plots of the residuals to match. This is a two-fold problem in that SAS has changed with ods graphics and my code does not produce matching covariance and correlation values for the residuals. I would like the acf and pacf covariances and correlations to be stored so I can retrieve their values. My SAS code is included below: ods graphics on; proc arima data=ultraShine plots(unpack)=series(acf pacf); identify var=y(1); estimate p=1 method=CLS maxit=4 printall; outlier; forecast lead=10 out=forecasts; run; The source code, data and Bowerman results are given in the enclosed files. I am using sas studio -demand edition. Can you help? Thank you. MM
