## Issue with Numerics

- Discretise
	- List values of attribute
	- Sort asc
	- Write class under each value
	- Breakpoints between change in class
	- Interval assigned to majority class
	- Enforce bucket size, if adjacent interval has same class, merge.

## Issue with Missing Values

- Assign "missing" as a value
- Treat normally

## Issue with Overfitting

- Bucket Enforcement
- Ensure attribute tested is applicable
