Chapter 1. A Quick Walk Through You and I are going to start our conversation by taking a quick walk through some of EViews’ most used features. To have a concrete example to work through, we’re going to take a look at the volume of trade on the New York Stock Exchange. We’ll view the data as a set of numbers on a spreadsheet and as a graph over time. We’ll look at summary statis- tics such as mean and median together with a histogram. Then we’ll build a simple regres- sion model and use it for forecasting. Workfile: The Basic EViews Document Start up a word processor, and you’re handed a blank page to type on. Start up a spreadsheet program, and a grid of empty rows and columns is pro- vided. Most programs hand you a blank “document” of one sort or another. When you fire up EViews— no document—just an empty window with a friendly “Welcome to EViews” message at the bottom. Because there aren’t any visual clues on the opening screen, setting up a new document in EViews sometimes bewilders the new user. While word processor documents can start life as a generic blank page, EViews documents—called “ workfiles ”—include information about the structure of your data and therefore are never generic. Consequently, creating an EViews workfile and entering data takes a couple of minutes, or least a couple of seconds, of explanation. In the next chapter we’ll go through all the required steps to set up a workfile from scratch. Being impatient to get started, let’s take the quick solution and load an existing workfile. If you’re working on the computer while reading, you may want to load the workfile “nysevolume.wf1” using the menu steps File/Open/EViews Workfile… as pictured on the next page.
