[Rsiena-help] Bipartite network analysis in Rsiena

[Matthew Weber]

Ruth,

Thanks so much for your email.

I'm trying to use an adjacency matrix, and having checked against the
session file you sent, I've set the session up correctly.

I agree that the problem may be the data format, but I have been unable to
find an example of the correct format for bipartite data in Siena Net format
(even in the manual)... Is there somewhere I can find this information, or
find a sample file that I can mimic?

Thanks Again,
Matt
