Hello,
I'got a base on PSPP which has only three columns: id, gender and
height.
I need to, for each male, to find the female who has the closest
height of this male.
On a pseudocode, it would be very easy (it is not optimized at all):
for (i=0;i<numcases;i++) {
if (bank[i][gender] = 1) break;//only do it for males
delta = 1;
for (j=0;j<numcases;j++) {
if (bank[i][gender] = 0) break;//only compare with females
tmp = abs(bank[i]['height'] - bank[j]['height']);
if (tmp < delta) {
delta = tmp;
bank[i]['match'] = bank[j]['id];
}
}
}
How do I do it on PSPP? I've searched on the docs, but coudn't find a
loop structure or
something similar to it, since I need to walk on all the cases twice.
Thank you!
Michel
