How to Score Data Using Proc NLIN?

ThePirate — Thu, 14 May 2015 01:43:25 GMT

Hello,

I am new at SAS and SAS EM and I am not sure how to score data using my model when I am using Proc NLIN. It seems that Proc Logistic has an option to score the data, but not Proc NLIN. Any ideas?

Append your score data set to the training data set.

Then run PROC NLIN with the OUTPUT statement.

Hello Mr. Gergely,

Could you please extend it? I did not get how to put score date set to the proc nlin without disturbing parameters created by train data. Is it possible you to put a small example showing both training and scoring?

Thanks,

If an observation contains missing value for the target, that observation is not used to fit the data.

data to_score;/*weight is not included!*/
name='NewStud';age=15;height=50;output;
run;

data all;
set sashelp.class to_score;
run;

proc nlin data=all;
parms b0=1 b1=1 b2=1;
model weight=b0 + b1*height + b2*age;
output out=result predicted=p_weight;
run;
