Hi there,

Could someone point me to where in the code hidden variables are dealt
with? How does pebl deal with calculating likelihoods when some data
are missing?

Thanks,
Matt

Hi Matt,

Pebl uses Gibb's sampling to calculate likelihoods with missing data. The relevant code is in evaluator.py, in the MissingDataEvaluator class:

Thanks,

Abhik.
