[statnet_help] TERGM for weighted networks

Hi Vivek (and list),

Stochastic actor oriented models can handle 2 different strengths of ties (last time I checked) with a dynamic framework. Although not ERGMs, it still might be of interest.

Check out the RSiena scripts on this page, http://www.stats.ox.ac.uk/~snijders/siena/ I think script #11 fits a dynamic network model that is “ordered” (i.e. ties with different weights). You’ll probably need to look at the manual and the more simple scripts first though to make sense of it.

Hi Pavel,
Thanks for letting me know! In my setting, the weights are just counts that represent the number of observed co-occurrences between words in a co-occurrence network.

Dear Vivek,

ERGM-based modelling of dynamic weighted network is an open problem,
which I am hoping to tackle in the next year or so. In the meantime,
can you tell me what the weights are in this case? Counts? Categories?
Ranks? Values between 0 and 1?
