The Binning Explorer app enables you to interactively bin credit scorecard data. Use the Binning Explorer to:
Select an automatic binning algorithm with an option to bin missing data.
(For more information on algorithms for automatic binning, see autobinning
.)
Shift bin boundaries.
Split bins.
Merge bins.
Save and export a creditscorecard
object.
Note
When using the Binning Explorer app with MATLAB Online:
The App toolbar is not available for MATLAB Online. To access
Help, from the MATLAB® command prompt, enter doc
binningExplorer
.
MATLAB Online does not display predictor information using three panels (Overview, Bin Information, and Predictor Information) in the Binning Explorer window. Instead, MATLAB Online displays these panels as tabs labelled Overview, Bin Information, and Predictor Information.
When performing manual binning, selected predictors are displayed in a tab in the Binning Explorer window. When you close the tab for a predictor, you do not return to the Overview panel. To return to the Overview panel, click the Overview tab.
Binning Explorer complements the overall workflow for developing a credit scorecard
model. Use screenpredictors
to pare
down a potentially large set of predictors to a subset that is most predictive of the
credit score card response variable. You can then use this subset of predictors when
using Binning Explorer to create the creditscorecard
object.
