Hello, I want to put a restriction on my intercept :
proc reg data=data;
model a= b c d;
restrict intercept = is;
run;
But I have an error "Variable is is not in the model. The restriction cannot be applied". But "is" is in my data.
Thanks for your help,
Lucie
Put the value of is into a macro variable, like this:
proc sql;
select mean(is) into :is from data;
quit;
proc reg data=data;
model a= b c d;
restrict intercept = &is;
run;
(untested)
If you want to restrict the intercept to some value, such as 33, then
restrict intercept-33=0;
Put the value of is into a macro variable, like this:
proc sql;
select mean(is) into :is from data;
quit;
proc reg data=data;
model a= b c d;
restrict intercept = &is;
run;
(untested)
Thank you a lot it worked !
