Proc PLAN: Randomly Assign 7 people to three groups evenly

[daszlosek]

Hello,

I have 6 people who can review 400 documents. I wish to have 3 reviewers assigned to each document. I would like, roughly, an even number of documents read by each reviewer.

I believe proc plan can help with the scenario, but I am having difficulty coming up with the code for it. 

Best,

Not sure about PROC PLAN but a data step is easy enough:

*Plan data;
data plan;
seed=2017;
array rvw(3) reviewer1-reviewer3;
array person(6) (1 2 3 4 5 6);
do papers=1 to 400;
call rancomb(seed, 3, of person(*));
do i=1 to 3;
rvw(i) = person(i);



end;
output;
end;

keep papers review:;
run;

*check distribution;
proc transpose data=plan out=long prefix=reviewer;
by papers;
run;

proc freq data=long;
table reviewer:;
run;

Reeza, thank you! I was definitely over-complicating this. I guess I just got a little too excited to have a reason to use proc plan!

How about this?  

%mktbibd(b=400, k=3, v=6)

It makes a balanced incomplete block design.  It has 400 rows (documents), 3 columns (reviewers per document), and 6 reviewers (entries in the design).  (Which do I believe, the body of your message that says 6 or the header which says 7?)  You need SAS/IML and SAS/QC to run this.

Wouldn't be simpler for proc surveyselect ?

data plan;
do person=1 to 6;
output;
end;
run;

proc surveyselect data=plan method=srs sampsize=3 reps=400 out=want;
run;

proc freq data=want;
table person;
run;
