Comparing the classification of scores generated by models
Version:
Compare the classifications or segmentation of the scores generated by different models in terms of behavior, odds, gains, value, and discrimination as displayed in the comparison curves step.
-
In the Class comparison step, select one or more predictive models for analysis and click Analyze charts.
-
In the Model analysis charts workspace, analyze the data:
- To view the cumulative behavior for all models, click the Behavior tab.
- To view the improvement in the cumulative behavior over the average behavior in binary models, click the Lift tab.
- To view the cumulative odds for the extended binary models, click the Odds tab.
- To view the cumulative percentage of positive cases for all models, click the Gains tab.
- To view the cumulative value for binary and extended binary models, click the Value tab.
This tab is available only if you have a numeric predictor with type as value during data analysis. You can view the graph for all the value predictors by choosing the predictor from the drop-down list.
- To view the discrimination for binary and extended binary models, click the Discrimination tab.
- Optional:
To save the score data as a CSV file, click Export as CSV.
This file includes information about the cumulative score for cases.
- Analyzing models
In the Model analysis step you can compare and view scores of one or more predictive models in a graphical representation, analyze predictive models' score distribution, and compare the classification of scores of one or more predictive models.
