The Realtors' Commercial Leading Indicator for Brokerage Activity measures future commercial activity based on 13 variables — including job growth, unemployment claims, wholesale and retail sales and prices of real estate investment trusts – and it says that right now the broad recovery in commercial markets is expected to continue for the next six to nine months.
While central actors are often fairly obvious as the person to whom most other members are in contact, the social network algorithm that computes brokerage potential measures the extent to which the member lies on the shortest path between unconnected members which is far more difficult to see, especially across a whole network.

On the basis of our data, we can conclude that the hybrid model combining local and global measures of brokerage is able to better characterize significant behavior.
Panel A depicts an example network with nodes classified in three groups (coded by different colors); panel B shows the node scores for the local and global measures of brokerage.
Since we want s to lie in the interval [ 0, 1 ], we normalize the sum by the maximum possible count of the liaison role l in vector g, i.e. the score s ∗ that an ideal super-connector node would display in the network under study, i.e. s ∗ = 5 k max. Figure 3 illustrates how these two measures of brokerage operate.
Her comparative models varied the three network measures of brokerage, density and hierarchy across a network made up of a management group and two or more subgroups of different professionals.
The method illustrated in panel A uses a local measure of brokerage [9].
