Re: Model Comparison through log(p)

After learning a model GeNIe gave me an EM log likelihood or log(p)=-15. When we calculate P (the probability of the model given the data set) it appears to be a very small probability so does this show that my model is useless? Thanks

Cross validation in GeNIe with different proportions

I wanted to make cross validaliton for my model. In different resources they say we must divide our data into two parts like 70% for training and 30% for testing. There is a k-fold cross validation option in GeNIe but, as the manual explains, k-fold divides data into two equal parts. Do I have chanc...

Model Comparison through log(p)

Hello, GeNIe produces a log(P) or EM log-likelihood value after estimating a Bayesian model. This log(p) shows model accuracy and it can be used for model selection or comparison. However the only information about log(p) in the manual is that it is a score between minus infinity and zero. Can you p...
