Regression analysis. Validation.

[chintanpatel]

Hello, I have three varaibles a,b and c. I am performing multiple linear regression. Before performing it i divided my data-set into train data and validate data. train data i am using to build regression model. And i would like to validate my data using the model. The code to build regression model over my train data is given below. How can i use the result from regression model to validate my data ?

proc reg data=WORK.train alpha=0.05 plots(only)=(diagnostics residuals
        observedbypredicted);
    model c = a b/;
    run;
