4.3 Missing column pattern graph

4.4 Analysis

This is the graph that describes the missing column pattern. It shows that we have some missing values in the variables ‘emp_length’ and ‘annual_income’. The missing pattern shows that:
- 1. Most of the missing values are in the variable ‘emp_length’.
- 2. There is no record that has missing values in these two variables at the same time.
- 3. The missing values take only a small (about 5%) part in the total number of records.
In our analysis, we will simply delete those records with missing values.
