Regression excluding individual observations

[PaigeMiller]

Show the log for PROC MIXED where you used the SOLUTIONF option and it didn't work.

I run:

data a;
input x1 y study;
id = _n_;
datalines;
0 2 1
1 4 1
2 3 1
3 6 2
4 6 2
5 5 2
6 8 3
7 10 3
8 9 3
9 9 3
;
run;

proc mixed data=a;
ods output solutionF=parms;
class study;
model y = x1;
RANDOM study / SOLUTION;
run;

and the log was:

WARNING: Output 'solutionF' was not created. Make sure that the output object name, label, or path is spelled correctly. Also,

verify that the appropriate procedure options are used to produce the requested output object. For example, verify that

the NOPRINT option is not used.

The SOLUTION option is needed in the MODEL statement. (You may also want it in the RANDOM statement, but that doesn't seem to be what you are asking for in this thread)
