well, I thought I have.
But I really have problems in modeling or using my BN.
I have evidence for two nodes of twenty measured, so I'm really sure about it.
When I then use the sampling algorithms they variate my evidence values.
This is what I don't understand. That's why I asked for the ability of fixing nodes.
Don't know how to explain it better.
In my opinion it should be possible to restrict the sampling algorithms to defined nodes or it should be possible to invalidate nodes for the sampling.
Somewhere must be an error in my thinking.
