For multi-record case data, you specify three columns:
The default for multi-record case data is to assume that the data has two or more attributes with the names defined in the Attribute Name column. In this case, all transformations are performed on each attribute value. For example, suppose that the values of Attribute Name are "TENNIS BALLS" and "TENNIS RACQUETS". If you bin the table using the Discretize transformation, "TENNIS BALLS" and "TENNIS RACQUETS" will be binned separately.
If you click the Single Metric checkbox, the data is assumed to have one attribute; the name of this attribute is the name of the Attribute Name column itself. In this case, if you bin the table using the Discretize transformation, bin boundaries are based on all data in the Value column.
