I have problems in understanding the calculation of an account’s importance:
The technical reference explains in section 7.2 that o_ij denotes the weighted net flow from account A_i to A_j. But o_ij depends on \tilde{o}_ij which is (roughly) defined as \tilde{w}_ji - \tilde{w}_ij. However, this term describes the inflow to account A_i, not the outflow.
So in my opinion the formula should read: \tilde{o}_ij = \tilde{w}_ij - \tilde{w}_ji.
Did I misunderstand this section?
