Hi all. Thank you all so much for the help! Through all the responses I am understanding the basics better and sussed out a solution. Here is what I used to use the parameter estimates from data set (training), to another (validation).   /*Outputting Parameter Estimates*/ proc reg data=senstraining4 outest=regout; train: model v18=v6 v8 v9 v13 v14 v15; title "Regression Parameters Out"; run; proc print data=regout; title2 "Outest data from regout"; run;   proc score data=senstraining4 score=regout type=parms predict out=RScoreP; var v6 v8 v9 v13 v14 v15; run; proc print data=RScoreP; run;   proc score data=senstraining4 score=regout out=RScoreR type=parms; var v6 v8 v9 v13 v14 v15; run; proc print data=RScoreR; title "Negative Residual Scores for Reg"; run;   /*Using output parameter estimates on new data set*/ data validation; set newcounty; if mod(_n_,2) eq 1; *_n_ is the number of observation; obs=_n_; run; proc print data=validation; title "Validation"; run; proc score data=validation score=regout out=newpred type=parms nostd predict; var v6 v8 v9 v13 v14 v15; /*'train' name carries model over*/ run; proc print data=newpred; title "Data Scored"; run; ...
