StataCorp, a leading developer of software for data science, is proud to announce the launch of a major upgrade to its flagship product, Stata.
The new version, Stata 19, provides many substantive advancements—from new statistical features and expanded reporting to interface improvements designed to enhance how users interact with the software. Stata 19 builds on many features previously announced with StataNow, StataCorp’s continuous-release software that delivers new features and software enhancements as soon as they are certified ready by the development team. With StataNow, StataCorp regularly delivers new features to end users throughout the year.
The latest version of Stata introduces a wealth of substantive new features.
– Expanded machine learning – In Stata 19, you can build high-performance predictive models with the all-new H2OML suite of commands. Stata 19 empowers users to take advantage of machine learning via H2O to uncover insights from data when traditional statistical models fall short.
– New and expanded statistical methods – Stata 19 offers more than 20 major enhancements or additions to its already expansive suites of methods for statistical analysis. In addition to machine learning, expanded statistical areas include causal inference with the support of conditional average treatment effects (CATEs), panel data with high-dimensional fixed effects (HDFEs) and correlated random effects (CREs), Bayesian analysis with Bayesian variable selection, survival analysis with a marginal interval-censored multiple-event times Cox model, meta-analysis with correlations, resampling with Bayesian bootstrap, time series with instrumental-variables structural vector autoregressive (VAR) models, and much more.
– Enhanced reporting and tables – Building customizable and reproducible tables you can include in your reports is now even easier in Stata 19. It is easier to create, customize, and export a table in a single line of code. In addition, more Stata results can be used seamlessly in customizable tables.
– New features in graphics –Stata 19 offers new graphs, including heat maps, bar plots with confidence intervals, and range and point plots with spikes or capped spikes. There are improved labeling and control of box groupings for bar graphs, dot charts, and box plots. Also, more graphs allow you to vary the color of lines, markers, and other characteristics based on the values of a specified variable.
– Enhancements to the interface –There are many new features for editing Stata scripts (do-files), which include expanded autocompletion support, document templates, word and selection highlighting, code-folding enhancements, temporary bookmarks, and a new user interface for managing bookmarks.
– New enhancements with Python – Stata 19 expands the programmer-favorite PyStata, providing even more ways for Stata to interact with the Python programming language.
– LAPACK/OpenBLAS support – Faster and more modern implementation of LAPACK/OpenBLAS for numerical computations in Stata for Mac on Apple silicon. OpenBLAS is an open-source implementation of the BLAS that is optimized for modern hardware platforms.
– Mata programming – Programmers will enjoy many additions to the Mata matrix language, including the new least-squares solvers, and improvements to numerical derivatives and matrix inverse methods.
Stata is the package of choice for panel data, survival analysis, time series, survey data, longitudinal data, multilevel models, SEM, endogenous covariates, sample selection, Bayesian analysis, multiple imputation, LCA, causal inference, and much more. Stata makes modeling and inference easy for all types of outcomes – continuous, binary, ordinal, categorical, count, and fractional. Stata has both a point-and-click interface and a powerful, programmable, and reproducible command syntax.
Stata/MP lets you analyze data in less time on inexpensive multicore laptops and desktops as well as on multiprocessor servers. Use just 2 cores, and your analyses run in one-half to two-thirds the time compared with Stata/SE. Use 4 cores, and cut the time to one-quarter to one-half. Use more for even faster analyses. Stata/MP supports up to 64 cores/processors.
StataNow is Stata with continuous-release version of Stata that offers new features as soon as they are ready. StataNow provides access to new features as soon as they are certified ready by the development team. Those features are added to StataNow via updates as soon as they are available. Thus, StataNow provides access to new features sooner. For instance, StataNow 19 contains features that will also be part of a future major release, Stata 20.
Want to know how to conduct a basic data analysis using Stata 19? We show you just that. Watch as we show you how to import data into Stata from Excel, how to change the display format of a variable, how to label variables and the values of categorical variables, how to create new variables, how to describe and summarize variables, and how to create several kinds of graphs. Next, we demonstrate how to fit a linear regression model, calculate and graph marginal predictions from the model, and send those commands to Stata’s Do-file editor. The video ends with a discussion of how to learn more about Stata using the Help files, PDF documentation, and the search command.

* 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.
