GRADBOOST Procedure

OUTPUT Statement

OUTPUT OUT=libref.data-table <option>;

The OUTPUT statement creates an output data table that contains the results of running PROC GRADBOOST.

You must specify the following option:

OUT=libref.data-table

names the output data table for PROC GRADBOOST to use. You must specify this option before any other options. libref.data-table is a two-level name, where

libref: refers to a collection of information that is defined in the LIBNAME statement and includes the library, 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 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 to be transferred to the output data table.

ROLE<=name>

generates a numeric variable that indicates the role played by each observation in fitting the model. By default, the variable is named _ROLE_. You can add an optional =name to change the name of this generated variable. For each observation, the interpretation of this variable is shown in Table 5.

Table 5: Role Interpretation

Value	Observation Role
0	Not used
1	Training
2	Validation
3	Testing

If you do not partition the input data by using a PARTITION statement, then the value of the role variable is 1 for all observations.
