[Rsiena-help] RSiena: Error using multiple processors

[Philippe Sulger]

Dear Tom,

Thank you. I am now running unconditional estimations. The loop seems to 
work. I got also an output for i=16; in fact - the rate function does 
not seem to be appropriate for this particular network (very high 
parameter estimate and standard error).

Best,
Philippe
