EViews 12 Compatibility Notes
The following discussion describes EViews 12 compatibility issues for users of earlier versions.
Workfile Compatibility
With few exceptions, EViews 12 workfiles are backward compatible with EViews 10. Note that the following objects are new or have been modified in Version 11:
• Estimation objects estimated with methods that employ new features (functional coefficients, elastic net, FI(E)GARCH, variable selection, indicator saturation, MIDAS with gets, panel and pool estimators with new cluster robust covariances, or degrees-of-freedom corrections).
If you have saved workfiles containing any of the above objects and open them in earlier versions, EViews will delete the incompatible object and notify you that one or more objects were not read. If you then save the workfile, you will lose the objects. We recommend that you make a copy of any workfiles that contain these objects if you would like to use these workfiles in earlier versions of EViews.
Computational Compatibility
• EViews 12 panel and pool estimators with cluster style robust covariances now employ a stronger degrees-of-freedom correction that is more in line with the cluster literature. The new correction will adjust coefficient standard errors downward to a greater degree than before. Because of this difference, estimators using these new corrections are not backward compatible.
