Degree centrality in 2-mode networks: how are percentages calculated

[Nina Abzianidze]

Hi,

I am trying to do the degree centrality analysis of a 2-mode network. Since I would like to be able to compare centralities across different networks, I need to have a measure that is normalized/standardizes. For the same purposes in one-node networks I have used "percentages" and it was clear that raw degree centralities were divided by the number of all the lines present in a network. This time with 2-mode network I did the same but I could not figure out what number is used for the division (i.e., "percentages" of what)?

Could you please tell me, how exactly is the degree centrality "percentages" in 2-mode networks are calculated? 

I, Hereby, would be grateful if you could also tell me how are the standardized degree centralities calculated for 2-mode networks?

FYI: I submit for the analysis single relation 2-mode network with valued data (i.e. how frequently an actor attends an event)

Thank you in advance and looking forward to hearing from you back.

1-mode and 2-mode networks are treated the same way.

"percentage" (for any centrality) scales the raw value such that the
centrality values of all nodes sum up to 100%.

"standardize" (for degree centrality, n>1) divides the raw value by (n-1).

Many thanks for your reply and the clarifications!
