Most regresion procs have plot functions. See example below.


data t1;
a=0.5123; b=0.72135;
do x=0.1 to 2 by 0.05;
y=a*(1-exp(-b*x)) + 0.1*rannor(123);
output;
end;
drop a b;
run;


ods graphics on;

proc nlin data=t1
NLINMEASURES plots(stats=all)=(diagnostics);

parms a=1 b=1;
model y=a*(1-exp(-b*x));
run;

ods graphics off;
