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:
|
|
|
Specifies the function
that a variable performs in determining a score code.
|
|
Specifies the name of
the variable that is being compared.
|
|
Specifies the name of
the variable attribute that is being compared.
|
|
Contains the value of
the attribute for the first model.
|
|
Contains the value of
the attribute for the second model.
|
|
Specifies an X if the
value of the variable attribute is different from the value of the
variable attributes in the other model. If the value of the variable
attribute is the same, this column is blank.
