Hi,
I have a question about the posterior probability distributions that are calculated for the individual nodes. Does GeNIe rounds the values up or down? I've been testing different combinations of input evidence and I experienced a few times that the probability distribution of individual nodes sometimes added up to either 99 or 101%.
Posterior probabilities rounded?

Re: Posterior probabilities rounded?
The rounding is performed only for display purposes (the actual calculations are done using double precision floating point numbers).I have a question about the posterior probability distributions that are calculated for the individual nodes.
I assume you're asking about rounding in the barchart display of the nodes. The algorithm rounds up when the first non displayed digit is 5 or greater, or down otherwise.
Note that you can increase the display precision using Tools|Options|Decimals in chance node barcharts.
