An X validated question as to why the MLE is not necessarily (well) covered by a posterior distribution. Even for a flat prior… Which in restrospect highlights the fact that the MLE (and the MAP) are invasive species in a Bayesian ecosystem. Since they do not account for the dominating measure. And hence do not fare well under reparameterisation. (As a very much to the side comment, I also managed to write an almost identical and simultaneous answer to the first answer to the question.)

The weather was fantastic: cold enough to trust the ice, but without the freezing wind of the past days. The approach walk is quite easy from the Lake Louise parking lot, following the edge of the (frozen) lake for about 20 minutes (the only worry being to have to step away from the horse-sleight bringing tourists to the end of the lake).
