Thanks. The problem gets deteriorated - I cannot open the network once it's collapsed. Can I send you the collapsed file in private?

Urgent - errors in LEAK column
This situation has occurred several times recently - the LEAK column of some nodes de-normalised itself with random numbers assigned to its states every time opening the node. Regardless how many times I re-normalised it, the error occurred again and again. The only fix seems to be deleting the node...

Re: Any advice on modelling a variable with combined prohibiting and promoting effects?
At my end, I used this way to get around it - to add a pseudo state named e.g. "NotForUse" for the parent and child nodes, and let this state be the distinguished state for the parents and the bottom state for the child. Forced 1 will then fall at the bottom-right cell to release the real ...

Re: Any advice on modelling a variable with combined prohibiting and promoting effects?
I studied the model. The states of the model are binary which somewhat marred the issue. If the states are expanded to multiple e.g. No accident, Light injury, Serious injury, and Fatal for Accident node, and Serious, Medium, Light, Without for both Equipment Failure and Human Error nodes, the probl...

Re: Any advice on modelling a variable with combined prohibiting and promoting effects?
Thanks Marek. It will be so merciful of you if a noisy-Min/And node is made available. I already studied the "accident" example in the user manual. In terms of the meaning, I tried to explain to myself this way: noisy-Min node is to maximise the opportunity of realising the most strengthen...

Re: Any advice on modelling a variable with combined prohibiting and promoting effects?
Yes I understand how to get a NoisyMIn negating the NoisyMAX but don't know how to deal with the distinguished state after that. The original distinguished state of the parent variable is no longer the distinguished state after negation (changing the order) and the top state is now forced to become ...

Re: Any advice on modelling a variable with combined prohibiting and promoting effects?
You're certainly right, Marek. But in real situations there are often more than 2 parents and more than 2 status for each node. But a more important reason is of course I love to have the logicality taste in the model instead of a kind of "random" guess during knowledge elicitation. I trul...

Re: Impossible status
Right, try to change the status of a deterministic node without a parent.

Impossible status
Just a simple question - the status of a deterministic node cannot be changed using "set evidence", right? Why's that? It's quite inconvenient.

Re: Any advice on modelling a variable with combined prohibiting and promoting effects?
Neither noisy-or or noisy-and applies. I used a noisy-adder the moment but don't feel fully satisfied.

Any advice on modelling a variable with combined prohibiting and promoting effects?
The case is like this: to evaluate a program that selects a fixed number of items for quality from a batch of them. Two parent variables - one for the stringency of the selection (X), one for the overall quality of the batch (Y). The resultant variable is the quality of the selected ones (Z). The co...

Just a small and humble suggestion
Is it possible to explicitly include a noisy-add (noisy-min) chance node as a choice? The negation of noisy-or gate is not very intuitive to the audience during expert elicitation (sometime me myself got messed up when there is a heated debate). It also presents awkwardly e.g. states being upside-do...

Re: Advice please on canonical model
Thanks, Marek. It makes sense, but I would still prefer to have the choice of hiding the constrained columns. This is why - sometime I have a row of say 10 parent nodes. The parameter data were prepared in Excel spreadsheets as such that can be readily copied to GeNIe. If no constrained columns I ca...
