Stata is a complete, integrated statistical package that provides everything
you need for data analysis, data management, and graphics. Stata is not sold
in modules, which means you get everything you need in one package. And,
you can choose a perpetual license, with nothing more to buy ever. Annual
licenses are also available.
12 adds many new features such as structural equation
modeling (SEM), contrasts, ARFIMA, business calendars, chained equations
for multiple imputation, contour plots, automatic memory management,
importing and exporting of Excel files, and more.

New in Stata 12.
Stata puts hundreds of
statistical tools at your fingertips, from advanced techniques, such as
survival models with frailty, dynamic panel data (DPD) regressions,
generalized estimating equations (GEE), multilevel mixed models, models with
sample selection, multiple imputation, ARCH, and estimation with
complex survey samples; to
standard methods, such as linear and generalized linear models (GLM),
regressions with count or binary outcomes, ANOVA/MANOVA, ARIMA, cluster
analysis, standardization of rates, case–control analysis, and
basic tabulations and summary statistics.
Complete data-management facilities
Stata’s data-management commands
give you complete control of all types of data: you can combine and reshape
datasets, manage variables, and collect statistics across groups or
replicates. You can work with byte, integer, long, float, double, and
string variables. Stata also has advanced tools for managing specialized
data such as survival/duration data, time-series data, panel/longitudinal
data, categorical data, multiple-imputation data, and survey data.
Stata makes it easy to generate
publication-quality, distinctly styled graphs, including regression fit
graphs, distributional plots, time-series graphs, survival plots, and
contour plots. You can write scripts to produce hundreds or thousands of
in a reproducible manner and export them to EPS or TIF for publication,
to PNG for the web, or to PDF for viewing. Or,
with the integrated
Graph Editor you click to
change anything about your graph or to add titles, notes, lines, arrows,
You can choose between existing graph styles or create your own.
Stata is so programmable that developers and users add new features every
day to respond to the growing demands of today's researchers. With Stata’s
new features and
official updates can be installed
over the Internet with a single click. Many new features and informative
articles are published quarterly in the refereed
Stata Journal. Another great
resource is Statalist, an independent listserver
where more than 4,500 Stata users exchange over 1,500 postings and 50
programs each month.
Though you don’t need to program to use Stata, it is comforting to
know that a fast and complete matrix programming language is an integral
part of Stata. Mata is both an interactive environment for manipulating
matrices and a full development environment that can produce compiled and
optimized code. It includes special features for processing panel data,
performs operations on real or complex matrices, provides complete support
for object-oriented programming, and is fully integrated
with every aspect of Stata. Learn more about
Stata will run on Windows,
Unix computers (including
Linux); however, our licenses are
not platform specific. You can install your Stata license on any of the
supported platforms. Stata datasets, programs, and
other data can be shared across platforms without translation.
You can also quickly and easily import datasets from other statistical
packages, spreadsheets, and databases.
Complete documentation and other publications
Stata comes with 21 volumes of
documentation containing more than 9,000 pages of information that
include calculation formulas, detailed examples, and references to the
literature. The documentation comes in PDF
form with every copy of Stata
and printed volumes are available either separately or as a set. Our
website is a great resource for information about Stata, including answers to
frequently asked questions.
You can read informative articles about statistics and new Stata features in
the quarterly Stata Journal.
The Stata News is a quarterly
publication containing announcements of new releases and updates, training
schedules, new books, Conferences and Users Group meetings, new products,
and other announcements of interest to Stata users.
Stata Press also publishes
books about using Stata and
about statistical topics for professional researchers of all disciplines.
You can read the offical Stata blog, Not Elsewhere Classified (NEC), at
http://blog.stata.com. NEC will keep you up to date about all
things related to Stata. That includes product announcements from StataCorp and
from others, service announcements such as on-site and public training,
timely tips and comments, and news and advice related to the use of Stata.
The articles appearing in the blog are individually signed. NEC is written by the
same people who develop Stata, support Stata, and sell Stata. NEC is informal
but useful, and even entertaining.
You can also participate in short
courses sponsored by Stata or third parties in various locations.
Conferences and Users Group meetings, held in
many places around
the world, provide opportunities to meet other users and learn from the
experts, including the developers of Stata.
