SAS/Ets User's Guide 11. Provides detailed reference material for using SAS/ETS software and guides you through the analysis and forecasting of features such as univariate and multivariate time series, cross-sectional time series, seasonal adjustments, multiequational nonlinear models, discrete choice models, limited dependent variable models, portfolio analysis, and generation of financial reports, with introductory and advanced examples for each procedure. You can also find complete information about two easy-to-use point-and-click applications: the Time Series Forecasting System, for automatic and interactive time series modeling and forecasting, and the Investment Analysis System, for time-value of money analysis of a variety of investments | 92 F Chapter 3 Working with Time Series Data title Plot of USCPI Data proc plot data uscpi plot cpi date vaxis 129 to 137 by 1 run The plot is shown in Figure .

PROC TIMEPLOT can also print the data values as well as plot them. The following statements use the TIMEPLOT procedure to plot CPI in the USCPI data set. Only the last 14 observations are included in this example. The plot is shown in Figure .

See The TIMEPLOT Procedure in the Base SAS Procedures Guide for more information. Using PROC GPLOT The GPLOT procedure in SAS GRAPH software can also be used to plot time series data although the newer SGPLOT procedure is easier to use. The following is an example of how GPLOT can be used to produce a plot similar to the graph produced by PROC SGPLOT in the preceding section. title Plot of USCPI Data proc gplot data uscpi symbol i spline v circle h 2 plot cpi date run The plot is shown in Figure . 94 F Chapter 3 Working with Time Series Data For more information about the GPLOT procedure see SAS GRAPH Reference.
