See also this R example, which explains quite good the idea of minimum spanning trees (https://stackoverflow.com/questions/59624905/how-to-calculate-minimum-spanning-tree-in-r). Applied to spatial price comparisons, the Paasche-Laspeyres spread is calculated for the R*(R-1)/2 region pairs and then the minimum spanning tree is derived. The resulting bilateral indices are chained together.
