Summary

Using the Identify Unusual Cases procedure, you have spotted several cases that warrant further examination. These cases are ones that would not be identified by other validation procedures, because the relationships between the variables (not just the values of the variables themselves) determine the anomalous cases.

It is somewhat disappointing that the peer groups are largely constructed based on two variables: Dead on arrival and Died in hospital. In further analysis, you could study the effect of forcing a larger number of peer groups to be created, or you could perform an analysis that includes only patients who have survived treatment.
