Working with Data
In the following discussion, we describe EViews’ powerful language for using numeric expressions and generating and manipulating the data in series and groups. We first describe the fundamental rules for working with mathematical expressions in EViews, and then describe how to use these expressions in working with series and group data.
More advanced tools for working with numeric data, and objects for working with different kinds of data are described in “Working with Data (Advanced)”.
