[Rsiena-help] error using the GUI

[Ruth M. Ripley]

Dear Maarten,

I am replying to the message you sent to the help list: I have deleted the 
message from the help list as it was too large. I used the information you 
sent me direct to investigate the problem.

The error was because the estimation ran into problems, caused by the fact 
that values in off were always higher than the corresponding one in onl 
and this was respected in the simulation. I suspect it led to problems 
finding actors in onl who could make any changes.

You might have seen a note in the report:

Network off is higher than network onl. This will be respected in the 
simulations.

Since it seems impossible to fit any model with this constraint in place, 
you need to turn it off. Unfortunately this cannot be done via the gui.

You would need to do the following, each time you hit Apply in the 
gui (which recreates the data object):

1) save the data from the Model Options screen 
2) load it in to R
3) library(RSiena) 
4) mydata <- sienaDataConstraint(mydata, off, onl, "higher", FALSE)
5) save the data again.
6) in siena01Gui, use restart from saved session option.

Let me know if you need help finding out exactly how to do all this on a 
Mac.

Alternatively, I guess you could just fake your data a little and put a 
single 0 in off somewhere with a 1 in the same cell in onl. This should 
make it work OK without all the extra steps.

However, when I tried to estimate the model in the effects object the rate 
for off became very high, so estimation slowed down so seriously I stopped 
it. You probably need to try a different set of effects.

Regards,

Ruth
