The selection of "High Needs" locations
From the empirical data and from the generated polynomial model plots it is apparent that a small proportion of physical locations P are attributable to a very large service volumes S .
I designate "high needs" as locations \(P_{s>5,i}\) which are associated with more than 5 confirmed service visits per month to that location.
Accordingly, the result (count) of selection of P, where Sp >5 are shown below.
