Truly reproducible research

Lots of folks talk about reproducible research.
Stata has been dedicated to it for over 30 years.

We constantly add new features; we have even fundamentally changed language elements. No matter. Stata is the only statistical package with integrated versioning. If you wrote a script to perform an analysis in 1985, that same script will still run and still produce the same results today. Any dataset you created in 1985, you can read today. And the same will be true in 2050. Stata will be able to run anything you do today.

We take reproducibility seriously.

Real documentation

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 a Quick start 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 18,000 pages in 35 manuals. But don’t worry, type help my topic, and Stata will search its keywords, indexes, and even community-contributed packages to bring you everything you need to know about your topic. Everything is available right within Stata.

Trusted

We don’t just program 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 4.1 million lines of testing code that produces 5.8 million lines of output. We certify every number and piece of text from those 5.8 million lines of output.

Continuously Updated

Staying on the most up-to-date version of Stata is now easier than ever.

StataCorp continually develops new features to enhance Stata software, from the latest statistical methods to the best in reporting, data visualization, and the user interface. With StataNow™ you do not have to wait until the next major release to begin using new features. We will release new features as soon as they are ready so that you can take advantage of them right away.

Easy to use

All of Stata’s features can be accessed through
menus, dialogs, control panels, a Data Editor, a Variables Manager, a Graph Editor, and even an SEM Diagram Builder.
You can point and click your way through any analysis.

If you don’t want to write commands and scripts, you don’t have to.

Even when you are pointing and clicking, you can record all your
results and later include them in reports. You can even save the
commands created by your actions and reproduce your complete
analysis later.

Easy to grow with

Stata’s commands for performing tasks are intuitive and easy to learn. Even better, everything you learn about performing a task can be applied to other tasks. For example, you simply add if gender==”female” to any command to limit your analysis to females in your sample. You simply add vce(robust) to any estimator to obtain standard errors and hypothesis tests that are robust to many common assumptions.

The consistency goes even deeper. What you learn about data management commands often applies to estimation commands, and vice-versa. There is also a full suite of postestimation commands to perform hypothesis tests, form linear and nonlinear combinations, make predictions, form contrasts, and even perform marginal analysis with interaction plots. These commands work the same way after virtually every estimator.

Sequencing commands to read and clean data, then to perform statistical tests and estimation, and finally to report results is at the heart of reproducible research. Stata makes this process accessible to all researchers.

Easy to automate

Everyone has tasks that they do all the time—create a particular kind of variable, produce a particular table, perform a sequence of statistical steps, compute an RMSE, etc. The possibilities are endless. Stata has thousands of built-in procedures, but you may have tasks that are relatively unique or that you want done in a specific way.

If you have written a script to perform your task on a given dataset, it is easy to transform that script into something that can be used on all your datasets, on any set of variables, and on any set of observations.

See how easy automation is in Stata »

Easy to extend

Some of the things you automate may be so useful that you want to share them with colleagues or even make them available to all Stata users. That’s also easy. With just a little code, you can turn an automation script into a Stata command. A command that supports standard features that Stata’s official commands support. A command that can be used in the same way official commands are used.

Advanced programming

Stata also includes an advanced programming language—Mata.

Mata has the structures, pointers, and classes that you expect in your programming language and adds direct support for matrix programming.

Though you don’t need to program to use Stata, it is comforting to know that a fast and complete 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. Stata also has comprehensive Python integration, allowing you to harness all the power of Python directly from your Stata code.

What is StataNow?

First and foremost, StataNow is Stata. It is a continuous-release version of Stata that offers new features as soon as they are ready. StataNow is the result of our ongoing effort to deliver the best Stata—the most current Stata—to our users.

Before StataNow, most new features became available only at the time of a major release such as Stata 17, Stata 18, and so on. StataNow provides access to new features sooner. For instance, StataNow contains features that will also be part of a future major release, Stata 19.

To discover What’s included in StataNow™, click the ‘New Features’ tab above

The features in StataNow are fully tested, fully certified, well documented, version controlled (if needed), as well as polished to our customary high quality. These features are prioritized in the development cycle to be available as soon as they are ready so that users can take advantage of them right away. As always, all versions of Stata are updated regularly with any corrections and necessary improvements. You can view a list of all additions to Stata and StataNow since we shipped Stata 18.

The new features in StataNow are released continuously throughout the current release until the next major release. They are not released according to any preset schedule. All StataNow features are marked as such throughout the Stata website and the Stata documentation.

Because StataNow is Stata, when we mention “Stata” throughout our website and documentation, we also mean “StataNow”. We will be specific about StataNow for features available only in StataNow. And because StataNow is Stata, it is available in all editions (StataNow/MP, StataNow/SE, and StataNow/BE) and on all supported platforms (Windows, Mac, and Linux). Throughout the website and documentation, we will usually refer to just Stata/MP, Stata/SE, and Stata/BE for simplicity. If you have a StataNow license as described below, you can take this to mean StataNow/MP, StataNow/SE, or StataNow/BE.


How can I get StataNow?

All annual license holders have access to StataNow, regardless of whether you have an annual license or multiyear license or whether your institution has a site license. You can access the latest StataNow features by simply typing update all in the Command window or by asking your system administrator to update your Stata. Existing Stata 18 users may need to type update all twice. The first update will give you a Stata that knows how to update itself to StataNow. The second update will be StataNow. Then type help whatsnew to see the list of all features.

New users can obtain StataNow online, by navigating to ‘purchase or upgrade’ on this page

If you have maintenance for your license, please contact us via email, phone or live chat, to obtain new download and license information for StataNow.

If you have a perpetual license without maintenance or your maintenance or license has expired, contact us for your options.


How do I know if I already have StataNow?

When you start Stata, you will see StataNow on the splash screen. You can also type about and you will see StataNow on the first line.


How do I continue receiving new features in StataNow?

We are adding new features to StataNow continuously. To access these features, all you (or your system administrator) need to do is type update all in the Command window in StataNow. Then type help whatsnew to see the chronological list of all features.

    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.

    Whether you’re a student or a seasoned research professional, a range of Stata packages are available and designed to suit all needs.

    All of the following editions of Stata have the same complete set of commands and features and manuals included as PDF documentation within Stata.

     

    Stata/MP is the fastest and largest edition of Stata. Virtually any current computer can take advantage of the advanced multiprocessing of Stata/MP. This includes the Intel i3, i5, i7, i9, Xeon, and Celeron, and AMD multi-core chips. On dual-core chips, Stata/MP runs 40% faster overall and 72% faster where it matters, on the time-consuming estimation commands. With more than two cores or processors, Stata/MP is even faster.

    Stata/MP is faster-much faster. Stata/MP lets you analyze data in one-half to two-thirds of the time compared to Stata/SE on inexpensive dual-core laptops and in one-quarter to one-half the time on quad-core desktops and laptops.

    Stata/MP runs even faster on multiprocessor servers. Stata/MP supports up to 64 processors/cores.

    Speed is often most crucial …” with the updated version “Speed is often most crucial when performing computationally intense estimation procedures. A few of Stata’s estimation procedures, including linear regression, are nearly perfectly parallelized, meaning they run twice as fast on two cores, four times as fast on four cores, eight times as fast on eight cores, and so on. Some estimation commands can be parallelized more than others. Taken at the median, estimation commands run 1.8 times faster on 2 cores, 2.9 times faster on 4 cores, and 4.1 times faster on 8 cores.

    Stata/MP is 100% compatible other editions of Stata. Analyses do not have to be reformulated or modified in any way to obtain Stata/MP’s speed improvements.

    Stata/MP is available for the following operating systems:

    • Windows (64-bit processors);
    • macOS (64-bit Intel processors);
    • Linux (64-bit processors);

    To run Stata/MP, you can use a desktop computer with a dual-core or quad-core processor, or you can use a server with multiple processors. Whether a computer has separate processors or one processor with multiple cores makes no difference. More processors or cores makes Stata/MP run faster.

    For more advice on purchasing/upgrading to Stata/MP or for hardware queries, please contact our sales team.
