[Rsiena-help] ML estimation for 2-mode networks

[marco tonellato]

Dear all,

while trying out the new ML option with Revision 138 of RSiena on my
two-mode data (3 panels, 135x719 actors, very sparse networks), I
encountered this error when running it on multiple cores:

Error in robmon(z, x, useCluster, nbrNodes, initC, clusterString,
clusterIter,  :
  Not enough observations to use the nodes

Yet, when I switched to single core I was able to start the model, although
it's taking forever: after 3 hours on my server it's still at Phase 2
Subphase 1 Iteration 50 Progress: 4%

My effects object included just density and 4cycles, and the standard
initial values option was set to TRUE

Do you have any clues on how to proceed?

Thanks in advance,

Marco
