ABSTRACT
Now we generalize our study of location problems from two to k ≥ 3 populations. Again we are concerned with comparing the populations with respect to a measure of centrality. We designate the populations by P1, . . . , Pk and the corresponding sample sizes by n1, . . . , nk. Our bookkeeping will be facilitated by the use of double subscripts, e.g.,
X11, . . . ,X1n1 ∼ P1, X21, . . . ,X2n2 ∼ P2,
... Xk1, . . . ,Xknk ∼ Pk.
