PROC MIXED output

 

Nested data analysis in proc mixed 
I want to set up a nested 3-level model in proc mixed, say repeated observations within 'CS_No_stud' within 'pt_num_school' within g'roup_district'. I do something like:
 
proc mixed data=data noclprint covtest noitprint PLOTS(MAXPOINTS=NONE);
class pt_num_school group_district CS_No_stud;
model strut_neointimal_thickness= /solution ddfm=bw ;
random int/ sub=group_district;
random int/ sub=pt_num_school(group_district);
repeated / sub=CS_No_stud(pt_num_school *group_district) type=cs;
run;

 

then, the result is in attach file...

why group_district does not estimate??

please let me know~~~~ASAP

THANK YOU~~
