Stata 9 - Statistical Software for Professionals ($2000+)
Stata is a complete, integrated statistical package that provides everything you need for data analysis, data management, and graphics.
Stata 9 adds many new features such as linear mixed models, balanced repeated replications, and multinomial probit.
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.
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), models with sample selection, ARCH, and estimation with complex survey samples; to linear and generalized linear models (GLM), regressions with count or binary outcomes, ANOVA/MANOVA, ARIMA, cluster analysis, standardization of rates, and case–control analysis; to 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.
With no special graphics modes or separate modules,
Stata makes it easy to generate publication-quality, distinctly styled graphs, including regression fit graphs, distributional plots, time-series graphs, and survival plots.
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. Learn more about Mata.
Cross-platform compatible
Stata is available for Windows, Macintosh, and Unix computers (including Linux).
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.
