What are the different types of SAS functions commonly used in data manipulation and analysis?

Types of SAS Functions in Data Manipulation and Analysis

When it comes to data manipulation and analysis in SAS, there are several types of functions that are commonly used. These functions help in performing various operations on the data efficiently. Below are some of the key types of SAS functions:

1. Character Functions: Character functions in SAS are used to manipulate and perform operations on character data types, such as substrings, concatenation, and case conversions.
2. Numeric Functions: Numeric functions are used to perform mathematical operations on numeric values, including rounding, formatting, and trigonometric functions.
3. Date and Time Functions: SAS provides a range of functions to work with date and time values, such as calculating intervals, extracting components, and formatting dates.
4. Statistical Functions: These functions are used for statistical analysis, including calculating descriptive statistics, probabilities, and regression analysis.

In addition to these types, there are also other specialized functions available in SAS for specific tasks such as data cleaning, transformation, and validation.

Overall, understanding and effectively using these different types of SAS functions is crucial for successful data manipulation and analysis in SAS.
