STATA's expertise lies in the analysis of time based data. STATA provides not only the basic time series models like ARIMA but even the multivariate equivalents (VAR/VEC-Models) as well. Further you are able to model volatility using GARCH-models in STATA. Kaplan-Meier-curves are the way to analyse survival times, while mixed models help to analyse panel data. A mighty scripting language completes the package.

STATA produces all kinds of classical statistics. You can use it for descriptive statistics, hypothesis testing and visualization of data. Typically STATA is used in research and development. The large amount of different statistical methods helps scientists in all fields of applications (Social science, econometrics, epidimiology, medical research).

No matter if you are a student or a senior researcher, there is always the right version of STATA available: **STATA IC**,** STATA SE**, **STATA MP **and **STATA Small**.

**Arguments for Stata:**

- Used in research and development
- Wide range of statistical and graphical methods
- Comprehensive statistical software
- Flexible and especially powerful for analysis of time series
- Easy to learn but mighty scripting language

Stata statistical software is a complete, integrated statistical software 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.

Easy to learn yet fully programmable for the most demanding data management and statistical requirements.

With Stata's menus and dialogs, you can easily point and click or drag and drop your way to all of Stata's statistical, graphical, and data management features. You can completely reshape your data, create group-level variables for panel or longitudinal data, graph a receiver operating characteristics (ROC) curve or impulse-response function (IRF), perform a case-control analysis, estimate a random-effects count-data model or a Cox proportional hazards model, or compute marginal effects from a nonlinear estimator. You can even access the dialog boxes for each command directly from the online help system. T his is a great way to explore all of the capabilities of Stata.
