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.
Stata 15adds 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.
Fast, accurate, and easy to use
a point-and-click interface, an intuitive command syntax, and online
help, Stata is easy to use, fast, and accurate (see certification
results and FDA document compliance for details). All analyses can
be reproduced and documented for publication and review.
Responsive and extensible
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 Internet capabilities, 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
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 graphs 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, and text.
You can choose between existing graph styles or create your own.
Stata will run on Windows, Mac, and 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.
