Could you please explain me the meaning of the following Centrality Measures and the mathematical formulas used by yEd to calculate them ?

1) Graph centrality

2) Node betweenness centrality

3) Closeness centrality

Thanks in advance

There are numerous websites which describe these common centrality measures.

In short, the **closeness **value of a node is the inverse of the sum of its distances to all other nodes. **Graph centrality** is similar; the graph centrality value of a node is the inverse of the maximum distance to any other node. **Betweenness **considers shortest paths between nodes; roughly speaking, a node has a high betweenness if it is on many shortest paths between all other pairs of nodes.
