In SAS^® Model Manager, the Gini and KS statistics that are produced by performance monitoring are usually different from the same statistics that are produced in the Dynamic Lift report. The performance monitoring and Dynamic Lift report methods are different. The performance-monitoring Gini and KS statistics are produced using an approximate method that does not sort the observations based on the posterior probability variable.

If the distribution of the posterior-probability variable is skewed, then the two methods produce greater differences. Under this condition, the Dynamic Lift report is more accurate. 

You cannot configure performance monitoring so that it uses the more-accurate method.

Click the Hot Fix tab in this note to access the hot fix for this issue.

After you apply the hot fix, you can configure performance monitoring to use the more-accurate method. Configure using either of these approaches:

• Select project Start-up Code. Add the following line. This approach impacts all projects.
     %let _MM_USE_EM_ASSESS=1;
• Use a user-defined property to impact only a specific project. Add the following user-defined property for the project:
  • key: _mm_use_em_assess
  • value: 1
