### Create dummy variables in SAS - The DO Loop

· In creating dummy variables.
We essentially created new columns for our original dataset.
This recoding is called “ dummy coding” and leads to the creation of a table called contrast.
In these steps.
The categorical variables are recoded into a set of separate binary variables.
This technique is used in preparation for multiple linear regression when you have a categoric.
Just as a dummy is a stand- in for a real person. Dummy variable des einkommens
