EViews 12 Compatibility Notes
 
Workfile Compatibility
Census X-13 Compatibility
The following discussion describes EViews 13 compatibility issues for users of earlier versions.
Workfile Compatibility
With few exceptions, EViews 13 workfiles are backward compatible with EViews 12. Note that the following objects are new or have been modified in Version 12:
Estimation objects estimated with methods that employ new features (nonlinear ARDL and PMG, Difference-in-difference equations, Bayesian Time-varying Coefficient VAR, VECs with general deterministics inside the cointegrating equation).
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.
Census X-13 Compatibility
EViews 13 uses a newer version of the Census X-13 executable. The current shipping version will be at least as new as Version 1.1, Build 59. There may be differences in results from previous versions due to Census Bureau changes in the routines.
Note that the Census Bureau has tested this version of X-13ARIMA-SEATS on Windows 10 and indicates that it may work on previous Windows versions.
