With 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.
Broad suite of statistical capabilities

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, 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, and survey data.

Stata makes it easy to generate publication-quality, distinctly styled graphs, including regression fit graphs, distributional plots, time-series graphs, and survival plots. 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 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 2,800 Stata users exchange over 1,000 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, and is fully integrated with every aspect of Stata.
