Thanks, yes, this is an excerpt from Pearl's book, which I own and have read. I've definitely re-read that section several times while working on my blog post.
7. Bayesian Posterior: SD = SE?

Technically the answer to this is always no, since these two quantities have totally different conceptual meanings -- one is the SD of the marginal posterior distribution for a parameter, one is the SD of the sampling distribution of the estimate of the parameter. With that said, we might still...

Pasted from the TS chatbox: Jake: i'm working on a blog post about the whole unobserved-heteogeneity-in-logistic-regression thing Jake: it's like 1/3rd written spunky: I was curious of what was going on with that blog. I'm writing one post myself about a little surprising result within linear...
