Chapter 2. EViews—Meet Data When you embark on an econometric journey, your first step will be to bring your data into EViews. In this chapter we talk about a variety of methods for getting this journey started on the right foot. Unlike the blank piece of paper that appears (metaphorically speaking) when you fire up a word processor or the empty spreadsheet provided by a spreadsheet program, the basic EViews document—the workfile—requires just a little bit of structuring information. We begin by talking about how to set up a workfile. Next we turn to manual entry, typing data by hand. While typing data is sometimes necessary, it’s awfully nice when we can just transfer the data in from another program. So a good part of the chapter is devoted to data import. To get started, here’s an excerpt from the file “AcadSalaries.wf1”. This file, available on the EViews website, excerpts data from a September 1994 article in Academe , the journal of the American Association of University Professors. The data give information from a survey of salaries in a number of academic disciplines. The excerpt in Table 1: Academic Salary Data Excerpt shows average academic salaries and corresponding salaries outside of academics.
