PROC SCORE Statement

PROC SCORE DATA= SAS-data-set < options > ;

You can specify the following options in the PROC SCORE statement.

DATA=SAS-data-set: names the input SAS data set containing the raw data to score. This specification is required.
NOSTD: suppresses centering and scaling of the raw data. Ordinarily, if PROC SCORE finds _TYPE_=`MEAN', _TYPE_= `USCORE', _TYPE_=`USTD', or _TYPE_=`STD' observations in the SCORE= data set, the procedure uses these to standardize the raw data before scoring.
OUT=SAS-data-set: specifies the name of the SAS data set created by PROC SCORE. If you want to create a permanent SAS data set, you must specify a two-level name. (Refer to "SAS Files" in SAS Language Reference: Concepts for more information on permanent SAS data sets.) If the OUT= option is omitted, PROC SCORE still creates an output data set and automatically names it according to the DATAn convention, just as if you omitted a data set name in a DATA statement.
PREDICT: specifies that PROC SCORE should treat coefficients of -1 in the SCORE= data set as 0. In regression applications, the dependent variable is coded with a coefficient of -1. Applied directly to regression results, PROC SCORE produces negative residuals (see the description of the RESIDUAL option, which follows); the PREDICT option produces predicted values instead.
RESIDUAL: reverses the sign of each score. Applied directly to regression results, PROC SCORE produces negative residuals (PREDICT-ACTUAL); the RESIDUAL option produces positive residuals (ACTUAL-PREDICT) instead.
SCORE=SAS-data-set: names the data set containing the scoring coefficients. If you omit the SCORE= option, the most recently created SAS data set is used. This data set must have two special variables: _TYPE_ and either _NAME_ or _MODEL_.
TYPE=name | `string': specifies the observations in the SCORE= data set that contain scoring coefficients. The TYPE= procedure option is unrelated to the data set option that has the same name. PROC SCORE examines the values of the special variable _TYPE_ in the SCORE= data set. When the value of _TYPE_ matches TYPE=name, the observation in the SCORE= data set is used to score the raw data in the DATA= data set.

If you omit the TYPE= option, scoring coefficients are read from observations with either _TYPE_='SCORE' or _TYPE_='USCORE'. Because the default for PROC SCORE is TYPE=SCORE, you need not specify the TYPE= option for factor scoring or for computing scores from OUTSTAT= data sets from the CANCORR, CANDISC, PRINCOMP, or VARCLUS procedure. When you use regression coefficients from PROC REG, specify TYPE=PARMS.

The maximum length of the argument specified in the TYPE= option depends on the length defined by the VALIDVARNAME= SAS system option. For additional information, refer to SAS Language Reference: Dictionary.

Note that the TYPE= option setting is not case-sensitive. For example, the two option settings, TYPE='MyScore' and TYPE='myscore', are equivalent.
