***** To join INSNA, visit http://www.insna.org ***** Dear all: I currently have a dataset of an online social network with over 30,000 nodes. I want to use the p* model or Snijders' stochastic actor-based model to estimate the evolution of the network. However, the current programs (e.g., SIENA) do not allow the input data larger than 1,000 nodes. Can anyone give me some advices on the model estimation? Thanks, ZHANG Lun Dept.
