What is Stata?
Overview of the Stata environment
Stata is a full-featured statistical programming language for Windows,
Mac OS X, Unix and Linux. It can be considered a “stat package,” like
SAS, SPSS, RATS, or eViews.
Stata is available in several versions: Stata/IC (the standard version),
Stata/SE (an extended version) and Stata/MP (for multiprocessing).
The major difference between the versions is the number of variables allowed in memory, which is limited to 2,047 in standard Stata/IC, but can be much larger in Stata/SE or Stata/MP. The number of observations in any version is limited only by memory.

Strengths of Stata
What is Stata?
Stata/SE relaxes the Stata/IC constraint on the number of variables, while Stata/MP is the multiprocessor version, capable of utilizing 2, 4,
8... processors available on a single computer. Stata/IC will meet most users’ needs; if you have access to Stata/SE or Stata/MP, you can use that program to create a subset of a large survey dataset with fewer than 2,047 variables. Stata runs on all 64-bit operating systems, and can access larger datasets on a 64-bit OS, which can address a larger memory space.
All versions of Stata provide the full set of features and commands: there are no special add-ons or ‘toolboxes’. Each copy of Stata includes a complete set of manuals (over 6,000 pages) in PDF format, hyperlinked to the on-line help.
