Description
In method _compute_lower_bound of mixture.bayesian_mixture.py all the terms that should be in the lower bound aren't there.
That's normal for constant terms but for the others is there an explanation ?
(The formula in Bishop book is :

Research direction
Start in mixture.bayesian_mixture.py at _compute_lower_bound and compare its terms with the Bishop lower-bound formula linked in the issue. Trace the quantities used by that method and determine whether omitted non-constant terms are intentionally represented elsewhere or indicate an implementation problem. Done means documenting the explanation or identifying a reproducible correction, with relevant tests updated if behavior changes.
