Weighing the elements so each group represents 1/3 gives weights wA=1, wB=3/2, and wC=3/4.. Ordering observations gives w={.75, .75, .75, .75, 1, 1, 1, 1.5, 1.5}. Summing gives W={.75,1.5,2.25,3, 4, 5, 6, 7.5, 9}. And so r-withahat would be the 6th position. It works! [Almost worse than not finding the wiki page initially, I also realize I've solved this problem before: finding median given a histogram instead of individual measures. Did not see that they were both flavors of same problem.] | |
