hi,
my customers have different costs depending on how well they are detected as buyers / non buyers etc.
this relationship will be displayed in a coherence table (when getting the performance results), and I want to built a scoring function for the individual fields like : TRUE POSITIVE = 60€; FALSE POSITIVE = -5,7 €; etc... how can I reach the individual fields/variables of a coherence table to use them in functions?
(I wanted to go through the Data mining cup 2002 example...)
