Question: How can you identify and handle missing values in SAS?

Answer: Missing values can be identified using functions like NMISS or special operators like IS MISSING. Handling missing values involves using techniques such as imputation or excluding observations with missing values.

Example:

DATA non_missing_dataset; SET original_dataset; /* Exclude observations with missing values */ IF NOT MISSING(variable) THEN OUTPUT; RUN;
