Matrix distanceDiogo Melo
by any permutation matrix Ξ has null effect on its range. In other words, any permutation of the rows or columns of V N pro- duces a basis for N(1 T ); id est, R(ΞV N ) = R(V N Ξ) = R(V N ) = N(1 T ). Hence, the matrix inequality −V T N DV N ≻ ...

For the example, we use the distance matrix D above to obtain ca = (1/1 + 1/1 + 1/1 + 1/1 + 1/2)/5 = 27/30, cb = 17/30, cc = 21/30, cd = 24/30, ce = 21/30, cf = 20/30. Node a does not only have many connections and to other central nodes, but it is ...

To explore the impact of including distance measures and assumptions about their relationship to transmission likelihood, we developed a flexible framework to incorporate pairwise distances (for example Euclidian distances, travel times, or any quantifiable distance matrix) into our previously published infe...
