Tree-AS node fields options

On the Fields tab, you choose whether you want to use the field role settings already defined in upstream nodes, or make the field assignments manually.

Use predefined roles This option uses the role settings (targets, predictors and so on) from an upstream Type node (or the Types tab of an upstream source node).

Use custom field assignments. To manually assign targets, predictors and other roles, select this option.

Fields. Use the arrow buttons to assign items manually from this list to the various role fields on the right of the screen. The icons indicate the valid measurement levels for each role field.

To select all the fields in the list, click the All button, or click an individual measurement level button to select all fields with that measurement level.

Target. Select one field as the target for the prediction.

Predictors Select one or more fields as inputs for the prediction.

Analysis Weight To use a field as a case weight, specify the field here. Case weights are used to account for differences in variance across levels of the output field. For more information, see Using Frequency and Weight Fields.
