Core Components of SAS
SAS consists of several core components, each designed to address different aspects of data analysis and management. The Base SAS software provides the foundation, enabling data manipulation, reporting, and descriptive statistics. SAS/STAT and SAS/ETS (Econometrics and Time Series) offer advanced statistical procedures and econometric analysis tools, respectively. Additionally, SAS Visual Analytics and SAS Visual Statistics are designed for data visualization and advanced statistical modeling, providing an interactive environment for exploratory data analysis and predictive modeling.
SAS Programming Language
The SAS programming language is a key component of the SAS system, allowing users to write programs for data processing, statistical analysis, and reporting. It is known for its simplicity and flexibility, making it accessible to users with varying levels of programming experience. The language supports a wide range of data types and includes built-in procedures (procs) for tasks such as data manipulation, statistical analysis, and data visualization. SAS macros, which are essentially reusable pieces of code, enhance the programming efficiency and customization of analyses.
| Component | Description |
|---|---|
| Base SAS | Provides data manipulation, reporting, and basic statistical capabilities. |
| SAS/STAT | Offers advanced statistical procedures, including regression, time series analysis, and survival analysis. |
