Notable DocumentationUpdates
This section contains an overview of significant changes to the EViews 7 from the printed manuals, or errors in the printed documentation to which you should pay particularattention.
Database Incompatibility
EViews 7 format databases are not compatible with and may not be read by previous versions of EViews. EViews 7 offers the ability to save yourdatabase objects in a format that may be read by earlier versions by creating an EViews 6 database using the new “type=” option of dbcreate (p. 229) (in the Command and ProgrammingReference) and then copying objects and data as desired. Note that there may be EViews 7 objects and data that cannot be stored in a version 6 compatible database.
New Matrix Functions
Anumber of matrix functions were added to EViews 7 after the manuals went to press. These functions provide tools for unstacking a vector into a matrix, performing element comparisons,and returning matrix objects containing uniform and normal random numbers.
Unstack Vector Elements
Previously, the EViews @vec and @vech commands allowed users to stack the columnsof a matrix or lower triangle of a sym matrix into a vector. The new @unvec and @unvech functions allow for the reverse operations where one unstacks the elements of a vector into amatrix or lower triangle of a sym matrix. See @unvec (p. 516) and @unvech (p. 516) in the Command and Programming Reference.
Element Comparisons
The relational operators “>=”, “>”, “
