Stata is a complete, integrated statistical software package that provides everything you need for data analysis, data management, and graphics.
Fast, accurate, and easy to use
With both a point-and-click interface and a powerful, intuitive command syntax, Stata is fast, accurate, and easy to use.
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. See certification results and FDA document compliance for accuracy details.
Stata's graphical user interface
Stata puts hundreds of statistical tools at your fingertips;
Mata is a full-blown programming language that compiles what you type into bytecode, optimizes it, and executes it fast.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. We don't just write statistical methods, we validate them. The results you see from a Stata estimator rest on comparisons with other estimators, Monte-Carlo simulations of consistency and coverage, and extensive testing by our statisticians. Every Stata we ship has passed a certification suite that includes 2.3 million lines of testing code that produces 4.3 million lines of output. We certify every number and piece of text from those 4.3 million lines of code. Technical supportStata technical support is free to registered users. And, this is a case of getting much more than you pay for.We have a dedicated staff of expert Stata programmers and Statisticians to answer your technical questions. From tricky data management solutions to getting your graph looking just right. From explaining a robust standard error to specifying your multilevel model. We have your answers.Extensible Resources Community
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 specialised data such as survival/duration data, time-series data, panel/longitudinal data, categorical data, multiple-imputation data, and survey data.
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. With the integrated Graph Editor you click to change anything about your graph or to add titles, notes, lines, arrows, and text.
Stata makes it easy to generate publication-quality, distinctly styled graphs.
When it comes time to perform your analyses or understand the methods you are using, Stata does not leave you high and dry or ordering books to learn every detail.
Each of our data management features is fully explained, and documented, and shown in practice on real examples. Each estimator is fully documented and includes several examples on real data, with real discussions of how to interpret the results. The examples give you the data so you can work along in Stata and even extend the analyses. We give you Quick Starts for every feature showing some of the most common uses. Want even more detail, our Methods and Formulas sections provide the specifics of what is being computed and our References point you to even more information.
Stata is a big package and so has lots of documentation – over 14,000 pages in 27 volumes. But don't worry, type help my topic and Stata will search its keywords, indices, and even user-written packages to bring you everything you need to know about your topic. Everything is available right within Stata.
Stata will run on Windows, Mac and Linux/Unix computers; however, licenses are not platform specific.
That means if you have a Mac laptop and a Windows desktop, you don't need two separate licenses to run Stata. 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.View compatible operating systems »
