Thanks Shooltz! Let say I get this value in node social pressure : min: 0 max: 0.029 average: 0.004 Based on that value, can I say that if I change one parameter in CPT social pressure , then the probability value of the use product will change a maximum of 0.029 from the current probability? (with ...

Thanks Shooltz.

And what is the meaning of that number?
Let say I get this value:
min: 0
max: 0.029
average: 0.004

Hi, Could you help me to "modify" the result of tornado diagram in sensitivity analysis? I attach the images of sensitivity analysis and tornado here. (1) I set "use product" as the target node. in the sensitivity analysis, node "access" is redder than others. Then I co...

Hi, I have other questions regarding ROC. 1. If I have 2 states in my class node (yes-no), then ROC will give 2 figures: state 1 and state 2. The both AUC numbers are similar, but the graph slightly different. If I want to report the ROC, which graph should I use? Or it doesn't really matter which o...

Hi, another question regarding sensitivity. What I understood is the tornado diagram shows the influence of the specific state on the outcome/target node. if the value of that state changes, then the output will change in certain percentage. so the tornado diagram shows the most influential state. f...

Thanks for your answer Marek. Yes, I agree with you not to trust the CPT in this no-data nodes. The reason I still use these intermediate nodes is because I follow one theoretical concept and I have also about 10 nodes connected to the outcome node which are too many. So I "clustered" them...

Dear Marek, Thanks for your answer. Yes, that's my mistake. I have another question about EM algorithm. To construct my model, I follow one theoretical concept contain several layers from outer nodes to the outcome node. Unfortunately, I have no data on some intermediate nodes. But yes, EM give me C...

Thanks Marek for your kind help! If you don't mind, I have another question. :) I build a simple model about heart disease (please find the model in attachment). I define also all CPTs. I am trying to compare the Genie's result with manual bayes calculation (in order to improve my knowledge in bayes...

Thanks Marek!

Which variable do you mean? Yes I have variables with missing value both in some nodes (and also in outcome node (class node in case of validation analysis; is it allowed or not to have missing value in outcome node?).

Waiting forward for your answer. And again, Thanks a lot!

Dear Marek,

Previously I asked why I got nothing on my ROC curve. Could you help me to find out what the reason is please? I send you private message with my model and data. Thanks.

Best,
Daniel

Dear Shooltz, Thanks for your answer. Could you help me to answer these questions from my previous conversation please? 1. When perform parameter learning, we get log(p) value. Do I need to consider this value to evaluate my model’s performance? I see that closer to zero is better. My log (p) value ...

Hello, I have a question regarding validation method. I have two states in my outcome nodes, "yes" and "no". What I understood in BN is you get probability in your outcome node. But in validation method, we will get the accuracy meaning that if the model can predict or distinguis...

Dear Marek, I have some extra questions: 1. When perform parameter learning, we get log(p) value. Do I need to consider this value to evaluate my model’s performance? I see that closer to zero is better. My log (p) value is -1084380.522721 which is very high. 2. Is it possible to have illogical CPT ...

When I click the checkbox, green point appear in the left bottom corner (0,0).

Thanks Marek for all your answers. they're very helpful. If you don't mind, I have more questions :) 1. Have you tried looking at the output file? You can see the posterior probability distributions over the class variable for each of your data records Sorry, I did not get this. What do you mean by ...
