Calcite | Level 5


Hi all,

I have created a distance matrix using the following codes:

proc distance data=C02 out=dist method=Euclid;

var interval (pass_rate);

id contract_id;

run;

The distance metric is simply an absolute value of the difference between two pass rates. Now I want to square the difference for each single cell in the matrix, how I can do that?

Any input will be appreciated.

Thanks,

proc sql;
select distinct contract_id into :c separated by ' ' from dist;
quit;

data want;
set dist;
array ct{*} &c;
do i=1 to dim(ct);
ct{i}=(ct{i})**2;
end;
run;

proc print data=want;
run;

In SAS 9.4 at least, you can ask for METHOD=SQEUCLID to get squared distances. - PG
