Hi, I have a problem of graphical view. :(
I performed an uncertainty analysis through decisions nodes, one for each variable of my net. The problem is that with dashed informational arrows the graphical view become confused.
Is it possible to hide informationa arcs? Or delet them together?

Thank ...

Wow! You managed to crash GeNIe. Would you be willing to send us a network that achived this result? I really mean it -- GeNIe should not crash no matter what.

Since I had again problem with my net to which I added decistion nodes to some variables to test the sensitivty here is my ...

I try to analyse my network through the strength of influence tool also applying the "color of arcs" in two different cases.
The first one is the network as I created it (let say the "natural" network) and the other one is with the introduction of decision nodes to make the sensitivity analysis (as ...

Here's the MSc thesis which describes the implementation of 'Strength of influence' feature in GeNIe:

I read the MSc thesis and I find it very useful! I am interested in better understanding of the "color of arcs" tool to show ...

Yes, you can. Just add a decision node...

I tryed once and doesn't work very well. I had some problems with GeNIe and the software crashes. Moreover in the output window this message appear:
"Utilities not specified. Policies cannot be evaluated"
thus every time I work (e.g ...

If I built a network that is not an influence diagram can I make the sensitivity analysis with the addition of a Decision node "Sensitivity" as explained in the Tutorial 12? Thank you very much!

What is exactly a 'target node'? Is simply the variable you are interested in or is necessary that it has specific properties (e.g. could be performed a diagnosis test on this variable)?

The numbers that you will find in the tables for the sensitivity mode mean essentially gradients (i.e., first derivatives) of the function of the posterior probability of the targets over the parameter in question. If there are no targets, then the algorithm takes the average, I believe. I hope this ...

I am a GeNIe new user. I built a network and now I would like to do the sensitivity analysis using the sensitivity tool. I tried it but I didn't understand how it works.
I found the Helps information too general instead the reference paper too difficult (sorry, I am not a statistician :oops ...
