SAS/Ets 9.22 User's Guide 220. 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 | 2182 F Chapter 32 The VARMAX Procedure Consider the following example proc varmax data simul2 outest est model y1 y2 p 2 noint ecm rank 1 normalize y1 noprint run proc print data est run The output in Figure 32.67 shows the results of the OUTEST data set.
