Delta Reports
About Delta Reports
A Delta report compares the input, output, and target variable attributes for each of the variables that are used to score two candidate models. Delta reports display the differences in the variables of competing candidate models.
The report output is a table that groups the variables by the variable name. For each
variable, the reports lists the attribute value for each model and whether the attribute value is the same or different from
the other attribute values.
Here is a description
of each of the columns in the output of a Delta report:
