1. The problem statement, all variables and given/known data Explain the difference between posterior density and posterior distribution 2. Relevant equations NA 3. The attempt at a solution This isn't a homework question per se, but it will help with something I'm working on. Anyway, my textbook defines posterior distribution as: Likelihood * Prior Density/ ∫Likelihood X Prior Density However, it goes on to talk about posterior density without explicitly discussing the differences, and I can't tell if those two terms are interchangeable or not. For instance, one question asks me to find the posterior density of something, and another the posterior distribution. Any help with these concepts would be greatly appreciated!
