Programming This tutorial is an introduction to Stata emphasizing data management and graphics. A PDF version is available here. For a complementary discussion of statistical models see the Stata section of my GLM course.

Stata is fast and easy to use. In this tutorial I start with a quick introduction and overview and then discuss data management, statistical graphs, and Stata programming.

Why IBM SPSS software?

The tutorial has been updated for version 15, but most of the discussion applies to versions 8 and later. Version 14 added Unicode support, which will come handy when we discuss multilingual labels in Section 2. Version 15 includes, among many new features, graph color transparency or opacity, which we'll use in Section 3.

This tutorial focuses on the Windows version, but most of the contents applies to the other platforms as well. There are versions of Stata for bit and bit computers; the latter can handle more memory and hence more observations and tend to be faster.

All of these versions can read each other's files within their size limits. There used to be a small version of Stata, limited to about 1, observations on 99 variables, but as of version 15 it is no longer available. If you have a bit workstation change the program name to stataSE If you prefer Unix systems logon to our Unix server lotka via X-Windows and leave your job running there.

The window labeled Command is where you type your commands.

Stata then shows the results in the larger window immediately above, called appropriately enough Results. Your command is added to a list in the window labeled Review on the left, so you can keep track of the commands you have used.

The window labeled Variables, on the top right, lists the variables in your dataset. The Properties window immediately below that, introduced in version 12, displays properties of your variables and dataset.

You can resize or even close some of these windows. Stata remembers its settings the next time it runs. You can also save and then load named preference sets using the menu Edit Preferences. I happen to like the Compact Window Layout.

You can also choose the font used in each window, just right click and select font from the context menu; my own favorite on Windows is Lucida Console. Finally, it is possible to change the color scheme, selecting from seven preset or three customizable styles. One of the preset schemes is classic, the traditional black background used in earlier versions of Stata.

Starting with version 8 Stata's graphical user interface GUI allows selecting commands and options from a menu and dialog system. However, I strongly recommend using the command language as a way to ensure reproducibility of your results. In fact, I recommend that you type your commands on a separate file, called a do file, as explained in Section 1.

The GUI can be helpful when you are starting to learn Stata, particularly because after you point and click on the menus and dialogs, Stata types the corresponding command for you. Try typing the following excluding the dot at the start of a line, which is how Stata marks the lines you type: Commands can also be abbreviated; the documentation and online help underlines the shortest legal abbreviation of each command and we will do the same here.

The second command shows the use of a built-in function to compute a p-value, in this case twice the probability that a Student's t with 20 d. We list a few other functions you can use in Section 2. If you issue a command and discover that it doesn't work press the Page Up key to recall it you can cycle through your command history using the Page Up and Page Down keys and then edit it using the arrow, insert and delete keys, which work exactly as you would expect.

For example Arrows advance a character at a time and Ctrl-Arrows advance a word at a time. Shift-Arrows select a character at a time and Shift-Ctrl-Arrows select a word at a time, which you can then delete or replace.

A command can be as long as needed up to some 64k characters ; in an interactive session you just keep on typing and the command window will wrap and scroll as needed. Or just select Help Command on the menu system.

The Basics

Each help file appears in a separate viewer tab a separate window before Stata 12 unless you use the optionnonew. If you don't know the name of the command you need, you can search for it. Stata has a search command that will search the documentation and other resources, type help search to learn more.SPSS Tutorials - Master SPSS fast and get things done the right way.
