SHAPLEY Procedure

PROC SHAPLEY Statement

PROC SHAPLEY DATA=libref.data-table REFERENCEDATA=libref.data-table <options>;

The PROC SHAPLEY statement invokes the procedure. Table 1 summarizes the options in this statement.

Table 1: PROC SHAPLEY Statement Options

Option	Description
DATA=	Specifies the input query data table, which contains the query observation
IMPUTE=	Specifies how to impute missing values
LOGLEVEL=	Specifies a value to control the quantity and type of notes to print to the client log
REFERENCEDATA=	Specifies the input reference data table

You must specify the following options:

DATA=libref.data-table

names the input data table for PROC SHAPLEY to use. The default is the most recently created data table. 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 the data, 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 input data table.

REFERENCEDATA=libref.data-table

specifies the input reference data table. libref.data-table is a two-level name, where libref refers to the library, and data-table specifies the name of the input data table. For more information about this two-level name, see the DATA= option and the section Using CAS Sessions and CAS Engine Librefs.

You can also specify the following options:

IMPUTE=MEAN | NONE | WEIGHTEDMEAN

specifies the method to use for imputing the missing observations. You can specify the following methods:

MEAN: uses the mean to impute missing values of interval variables, and uses the mode to impute missing values of nominal variables.
NONE: does not impute missing values.
WEIGHTEDMEAN: uses the weighted mean to impute missing values of interval variables, and uses the mode to impute missing values of nominal variables.

By default, IMPUTE=NONE.

LOGLEVEL=0 | 1 | 2

controls the quantity and type of notes to print to the client log.

0: prints only warnings and errors.
1: prints some notes.
2: prints many notes.

By default, LOGLEVEL=1.
