7. Coding for merging two files
PROC SQL;
create table sasfile.final as
select L.* , R.*
from sasfile.Newfile as L
LEFT JOIN sasfile.Two as R
on L.index=R.index;
quit;
8. Coding for Correlation & Regression
Correlation
proc corr data= sasfile.final;
var EraHA2;
run;
quit;
Regression
proc reg data= sasfile.final;
model EraHA2=MD5CRDISX ;
run;
quit;
