imposing restrictions in linear models

[Amalik]

Hi,

I am using the following code to genrate a restricted regression but its not working, can someone please look into it?

proc nln data=temp1 noprint outest=Out_Estimates ;
restrict US_Small_Val + US_Small_Gr + US_Large_Gr + _US_Large_Val = 1;
bounds 0 <= US_Small_Val <= 1;
bounds 0 <= US_Small_Gr <= 1;
bounds 0 <= US_Large_Gr <= 1;
bounds 0 <= _US_Large_Val <= 1;
model AMP_AIT = US_Small_Val US_Small_Gr US_Large_Gr _US_Large_Val /noint;
run;
quit;

Describe how it isn't working: No output, error messages, unexpected output? If there are errors or warning you should include them. Anything that may be related to data is going to be purely a guess without your data.

Its says proc nln procedure not found

I assumed you misspelled it in the post:  Proc NLIN most likely.
