2. Model variables, P and Sp
Over the 10 year period \(i\in\left\{1..10\right\}\), I found 20,950 unique addresses (n(P)).
The total service counts across the same period was
\(\sum_{i=1}^{10}S_{p,i}\) = 104,861
I generated X-Y plots of unique locations ( P ) against total counts of service visits to those locations (Sp,i), over annual periods. These are shown below. The X-axis (P) is plotted in descending order of (Sp,i).
