The OUTPUT statement creates an output data table that contains the predicted values of the input data table.
You must specify the following option:
-
OUT=CAS-libref.data-table
names the output data table for PROC SVMACHINE to use. You must specify this option before any other options. CAS-libref.data-table is a two-level name, where
- CAS-libref
refers to a collection of information that is defined in the LIBNAME statement and includes the caslib, which includes a path to where the data table is to be stored, and a session identifier, which defaults to the active session but which can be explicitly defined in the LIBNAME statement. For more information about CAS-libref, see the section Using CAS Sessions and CAS Engine Librefs.
- data-table
specifies the name of the output data table.
You can also specify the following option:
-
COPYVAR=variable
COPYVARS=(variables)
lists one or more variables from the input data table that are transferred to the output data table.
-
ROLE<=variable>
specifies a numeric variable that indicates the role that each observation plays in fitting the model. The default name is _ROLE_. Table 2 shows how this variable is interpreted for each observation.
Table 2: Role Interpretation
| Value | Observation Role |
|---|
| 0 | Not used |
| 1 | Training |
| 2 | Validation |
| 3 | Testing |
If you do not partition the input data by specifying a PARTITION statement, then the role variable value is 1 for observations that are used in fitting the model and 0 for observations that have at least one missing or invalid value for the target or input variables.
