proc score predict option

[asifgeneral]

LGD modelling using Linear Regression

proc score data= Mydata score=tarin_estimate out=Reg_output (keep=RR model1)

predict type=parms;

var var1 var2 var3 var4... var14;

run;

I want to know about the option predict? Can you please help. Thanks

For questions like this, I go straight to the documentation

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.
