A Chernoff Face Diagram in Stata

Chernoff faces are a visual way of comparing different variables or different categories within a variable. The different elements of each face (like the eyes, hair, nose, etc.) will change depending on different values assiociated with the different variables or categories.

To create a Chernoff faces diagram in Stata, you first need to download the chernoff command from the Stata Journal Volume 9 Issue 3. To do this, you use the following commands in Stata:
