WebAny Networkx Graph can be used in this context; however there are restrictions in terms of the default features which are present in the library.Except MultiGraph (from Networkx), features which include centrality (degree,eigenvector,katz,betweenness,closeness) metrics can be used with any graphs (also with graphs converted from pandas dataframe). WebCompute the Katz centrality values using a computational tool. In networkx, use the default values of a = 0.1 and B = 1 for the networkx.katz_centrality function. Make sure your resulting centrality vector is normalized to Liv = 1 if necessary. Provide an answer accurate to at least three significant figures (graded to 1% tolerance). Web中心度计算在networkx中很容易，直接使用betweenness_centrality()就可以。这个方法会返回对应的NodeID以及对应的中心度值。如果normalized设置成True。那么原来的nodeid会除以node pair值。如果endpoints设置成True，那么终点节点也会被考虑到计算过程中。 endothelial dysfunction in men
