Tab missing allows you to see any observation that may have been dropped

Stata works really well for analyzing data. One of the things I like most about Stata is that there a lot of resources for different types of analyses you may need to do. You can Google almost any question you would have about Stata and have several articles that help answer your questions.

I find the interface easy to navigate. I like being able to see the data in spreadsheet format to scan for issues. I like the new graphics editor though... (see just below)
