Tips:Gini Coefficient in SAS
From sasCommunity
Gini coefficient is one of the many model statistics which is commonly used in data mining. However, it is not a part of the the proc logistic outputs. Most fortunately, Gini coefficient can be calculated easily by taking twice the c statistics and substracting 1 from it.
Gini = 2*C statistics - 1
Hope this will help those who need it.
