Forgive me if I am missing something obvious or if there is another thread about this topic. Background: I was relating to a colleague what I thought I had understood as a take-home message from among several posts on the older users group. That is: one should strive to have posterior distribution estimates (for "core parameters" if that makes any sense?) with roughly the same scale.
But, when asked why, I realized that I could not express a succinct reason, nor did I have a reference handy that discusses this issue. Can anyone help me here, either with some nice bullet points supporting this idea, or by pointing me to a good reference that discusses this.
Thanks in advance for any assistance you care to offer.
