***** To join INSNA, visit http://www.sfu.ca/~insna/ ***** I have a question for the collected wisdom of the list. I have data that contain (binary, undirected) ego networks which contain only one tie and am using ego density as a measure. Technically, density is undefined for networks of size 1. How have researchers dealt with this in practice? Have they excluded records containing such observations from statistical analysis (i.e., listwise deletion) or have they set density equal to zero in such cases? Are there other options to consider? Any suggestions would be most welcome. Thanks in advance.
