# Aside: More Missingness Examples¶

This notebook serves to provide more examples of how to identify missingness mechanisms through data.

## Example: Cars 🚗¶

### Example: Cars¶

• We have data on cars that were given tickets.
• For each car, we have their 'vin' number, 'car_make', 'car_year', and 'car_color'.
• Question: Is 'car_color' missing at random, dependent on 'car_year'?
• Is the distribution of 'car_year' similar when color is missing vs. not missing?
• How similar is similar enough?

Let's use a permutation test!
