SAS is one of the most sought after language commercially. The demand for SAS has been propelled by the fact that it's been the easiest to learn among all the software which is being used in the Data Science industry. SAS has a robust data handling and exhaustive Machine Learning capabilities which makes it almost indispensible skill set for a Data Scientist to have.
This tutorial will discuss about the tools that allow programs to “make decisions” based on data values. For example, you may want to read a value of Age and create a variable that represents age groups. You may want to determine if values for a particular variable are within predefined limits. Programs that perform any of these operations require
conditional processing—the ability to make logical decisions based on data values.
We are going to discuss the following topics:
Filter with if statement
Select Delete rows as per conditions
Boolean logic with if statement
