The DISCRIM Procedure |
To use this calibration information to classify observations in another data set, specify both of the following:
data original; input position x1 x2; datalines; ...[data lines] ; proc discrim outstat=info; class position; run; data check; input position x1 x2; datalines; ...[second set of data lines] ; proc discrim data=info testdata=check testlist; class position; run;
The first DATA step creates the SAS data set Original, which the DISCRIM procedure uses to develop a classification criterion. Specifying OUTSTAT=INFO in the PROC DISCRIM statement causes the DISCRIM procedure to store the calibration information in a new data set called Info. The next DATA step creates the data set Check. The second PROC DISCRIM statement specifies DATA=INFO and TESTDATA=CHECK so that the classification criterion developed earlier is applied to the Check data set.
