A deployed scoring model accumulates 30 days of production predictions. PSI = 0.22 is detected for the predicted score distribution. According to standard PSI thresholds, what action should be taken?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — c is correct because standard PSI thresholds are: PSI < 0.10 = negligible change (no action), 0.10 <= PSI < 0.20 = moderate change (monitor closely, investigate), PSI >= 0.20 = significant change (model may be unstable, escalate, investigate, consider retraining). PSI = 0.22 exceeds the critical 0.20 threshold.

C is correct because standard PSI thresholds are: PSI < 0.10 = negligible change (no action), 0.10 <= PSI < 0.20 = moderate change (monitor closely, investigate), PSI >= 0.20 = significant change (model may be unstable, escalate, investigate, consider retraining). PSI = 0.22 exceeds the critical 0.20 threshold. A is wrong; 0.22 > 0.20 is significant. B is wrong; PSI = 0.22 exceeds the moderate range into significant. D is wrong; SAS Model Manager can be configured to alert but does not automatically roll back.
