How does Stata work

The typical working screen is arranged into four panels, that you can re-size or re-arrange:

Top LH corner: Review: a list of previous commands
Bottom LH corner: Variables: a list of variables
Top RH corner: Results
Bottom RH corner: Command line for entering commands

Stata has two modes for use: interactive and batch.

In interactive mode sessions are run interactively from dialog boxes or the Stata command window. When using dialog boxes commands for statistics (with any options) and variable names are selected. The actual Stata commands also appear in the Review windows. Commands for data management or statistics may also be typed in (abbreviations are usually permitted). Variable names can be typed in (and may be abbreviated) or selected from the list of variables. Previous commands can be selected from the review panel and re-submitted after modification. In practice, the command line procedure is very fast. The analysis itself is incredibly fast. There is online help for all commands. In batch mode analyses are run from scripts (Stata do files). Stata is fully programmable so that users can create their own routines.

Most users run a log file for their session. This is in ASCII format and can be edited in a word processing programs or text editor. The list of review commands can be saved into a .do file for editing and subsequent use in batch processing. Graphical output can be copied into word processing programs or saved in various formats eg. wmf, ps, eps etc.

Looking at Stata

In order to see what Stata looks like, we have two suggestions:

Talk to a colleague who already has a copy. If you contact us we can probably give you the name of someone nearby who uses Stata.
If we cannot give you the name of someone nearby who uses Stata, we may be able to send you a fully functional evaluation copy of Stata. This will be valid for 35 days, to give you time to experience the speed and power of the program.
