Use this selection to define custom bin boundaries for a numerical attribute. Bins and their bin range are displayed as you define them.
You can generate default bins and modify them, or you can define bins directly by specifying lower bounds.
To generate default bins, click Generate Default Bins. You can then use Add to split a selected bin or Delete to delete one or more bins.
To explicitly define a bin, click Add. You can define new bin boundaries in one of two ways:
If you specify the value LOW
, this selection will create a bin consisting of values between MIN (the lowest value) and LOW
.
If you wish to have a largest bin with no upper bound, selected No upper bound from the Upper Bound pulldown list. The default is to have an upper bound equal to the maximum value.
To remove one or more bins, select them, and click Delete.
Click OK to return to the previous dialog.
The wizard calculates the bin boundaries and marks the attribute as using Run Binning strategy.
