[statnet_help] TERGM on ego networks

[Allan Clifton via statnet_help]

Hi all- I wanted to get some thoughts on how to analyze a dataset of ego
networks. We have about 500 participants, with longitudinal data gathered
at 6 assessment times. At each timepoint, they completed an egocentric
network of their 20 closest associates, which included connections between
alters (including allowing alters to enter or leave the networks) and
behavioral information about each alter.

We want to look at how these networks change over time, and how structural
and compositional changes in the network are related to behavioral change
in the egos. This seems like a question that TERGM would be appropriate
for, but I'm a little daunted about how to do this with 500 ego networks.

Many of the tutorials that I've viewed about ergm.ego use the ego networks
as a starting point to simulate larger networks. But we're instead
interested in examining these 500 networks to find commonalities or
patterns among our participants' behavioral change over time. Is it even
possible to use ergm.ego with longitudinal networks? Is there a better way
to approach this? Any suggestions of approaches to try, or resources to get
a better foundation on this type of data would be helpful.

Thank you!
Allan
