What’s New in SAS/ETS

PANEL Procedure

The PANEL procedure expands the estimation capability of the TSCSREG procedure in the time-series cross-sectional framework. The new methods include: between estimators, pooled estimators, and dynamic panel estimators using GMM method. Creating lags of variables in a panel setting is simplified by the LAG statement. Because the presence of heteroscedasticity can result in inefficient and biased estimates of the variance covariance matrix in the OLS framework, several methods that produce heteroscedasticity-corrected covariance matrices (HCCME) are added. The new RESTRICT statement specifies linear restrictions on the parameters. New ODS Graphics plots simplify model development by providing visual analytical tools.
