This is a general discussion of the data usage page. The exact information displayed depends on the model being built. For example, data for an association model has no target displayed.
If you are viewing this page from an activity, the activity may have made choices for you.
The wizard displays a list of the possible attributes to be used. You can include or exclude attributes, and you can change the data mining type and the datatype of attributes.
If the table is multiple record per case (transactional), then you must use numerical attributes.
The following information may be displayed for each attribute:
The Attributes Available grid contains all attributes except for the target attribute, which is listed above the grid.
The attributes are displayed in the attributes grid has the following columns:

.NUMBER
or FLOAT
, then the mining type is numerical
; you can change mining type to categorical
.categorical
.CHAR
or VARCHAR2
, the default mining type is categorical
; you can change it to text
if the algorithm that you selected supports text mining.
Note: Not all algorithms support text mining. See Text Mining for more information.
NUMBER
;
the mining type can be either categorical
or numerical
.
You can include or exclude attributes, as described in Including and Excluding Attributes.
To restore the original mining type defaults for all the attributes in the table, click Restore.
When you are done, click Next.
