Posterior Updates after New Evidence

Post by yysr »

Hi all,
I was working on Tut.3 and understand that by setting an evidence on "Expert forecast" node the "Success of venture" node's posterior gets updated and vice versa.
But if I'd like to see the posterior of the two nodes after I observed (set evidence) Good to "Expert forecast" and Failure to "Success of venture" how I can do this?
The little check-icon on right lower corner doesn't exist anymore.

Thanks!
Best Regards, YY

Hi YY,

You can update the network by pressing F5 (for updating once), or by pressing ctr-F5 (for continuously updating the network).
For a more convenient view of all posteriors you can select all the nodes, press the right mouse button and go to view as-> Bar chart.
This will show all nodes as bar charts showing you the (posterior) marginal distribution of the nodes. (Works very well with ctr-F5, you can double click a state of a node to update its evidence).

Best,

Martijn
