This article explains how to score a new data in a linear regression model with SAS.

**Build a linear regression model**

proc reg data = crime noprint outest=estimates;

model crime = pctmetro poverty single;

run;

quit;

**Note :**The

**OUTEST=**option returns a data set in which estimates are stored.

**Score a linear regression model**

proc score data = crime_new score=estimates

out=scored type=parms;

var pctmetro poverty single;

run;

- The
**TYPE=**option tells**PROC SCORE**what type of data the SCORE= data set contains. In this case, specifying**TYPE=PARMS**tells SAS to use the parameter estimates in the Estimates data set. - The
**VAR**statement specifies the variables to be used in computing scores. Specify independent variables to be used in computing predicted values.
