Part 10: How do you evaluate a model? · Module 23
Consistency: does the pattern keep its promise?
What Is Consistency?
CNA gives every solution two scores. The first is consistency , and it answers a simple question: when this combination of gaps is present, does low coverage actually show up too?
A consistency of 1.00 means every facility with the combination also had the outcome, so the pattern never let you down. A consistency of 0.80 means it held 80% of the time. Higher is better. CNA's default threshold is 1, and you lower it when real-world data gets noisy, which it always does.
What You Will Be Able to Do
- Define consistency in plain language.
- Read a consistency score.
- Set the con threshold when data is noisy.
