Why use Stata statistical software?


video: quick tour of Stata

Stata statistical software is a complete, integrated statistical software 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. Learn Which Stata is right for me.

Stata 13 adds many new features such as treatment effects, multilevel GLM, power and sample size, generalized SEM, forecasting, effect sizes, Project Manager, long strings and BLOBs, and much more. Find out more about these features at New in Stata 13.

Fast, accurate, and easy to use

With both a point-and-click interface and a powerful, intuitive command syntax, 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. Version control ensures statistical programs will continue to produce the same results no matter when you wrote them.

Broad suite of statistical features

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 features 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 (including BLOBs and strings up to 2 billion characters). 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.

Publication-quality graphics

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.

Responsive and extensible

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, a forum where more than 5,100 Stata users exchange over 1,500 postings and 50 programs each month.


Matrix programming—Mata

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 Mata.

Cross-platform compatible

Stata will run on Windows, Mac, and Linux/Unix computers; 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.

Stata comes with 20 volumes of PDF documentation containing more than 11,000 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. Our website is a great resource for information about Stata, including answers to frequently asked questions.
