About Stata 15

Why use Stata 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 that the scripts for your analyses will continue to produce the same results no matter when they were written. See certification results and FDA document compliance for accuracy details.

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 specialized data such as survival/duration data, time-series data, panel/longitudinal data, multilevel data, categorical data, multiple-imputation data, and survey data.

Stata makes it easy to generate publication-quality, distinctly styled graphs.

You can point and click to create a custom graph. Or, you can write scripts to produce hundreds or thousands of graphs in a reproducible manner. Export graphs to EPS or TIF for publication, to PNG or SVG 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.
