Stata is a complete, integrated statistical package that provides everything you need for data analysis, data management, and graphics.

Stata 10 adds many new features such as multilevel mixed models, exact logistic regression, multiple correspondence analysis, a graph editor, and time-and-date variables.

Easy to use

With a point-and-click interface, as well as an intuitive command syntax, Stata is easy to use, fast, and accurate. All analyses can be reproduced and documented for publication and review. Stata comes with complete documentation, including a Base Reference Manual set of over 1,600 pages with statistical examples and explanations, methods and formulas, and references to the literature.

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 over 1,000 postings and 50 programs are exchanged each month.

Outstanding technical support is free to registered users of Stata. Over half of our web site is devoted to supporting users of Stata.

Professional and powerful

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), models with sample selection, ARCH, and estimation with complex survey samples; to linear and generalized linear models (GLM), regressions with count or binary outcomes, ANOVA/MANOVA, ARIMA, cluster analysis, standardization of rates, and case–control analysis; to basic tabulations and summary statistics.

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. Stata also has advanced tools for managing specialized data such as survival/duration data, time-series data, panel/longitudinal data, categorical data, and survey data. You can also read datasets across platforms (Windows, Mac, and Unix) without translation and import datasets from other statistical packages, spreadsheets, and databases quickly and easily.

With no special graphics modes or separate modules, Stata makes it easy to generate professional-quality, distinctly styled graphs, including regression fit graphs, distributional plots, time-series graphs, and survival plots.
