Description

The discussion in #32 reminded me that one thing @andrewgelman and others have been wanting for a while (and that I think would also be useful as an alternative to the standard summary output) is a summary where each vector/matrix/array parameter only occupies a single line just like scalars. That is, each line corresponds to a named parameter rather than a parameter element.

(This could be its own thing or just an option to a custom print method for our existing summary objects.)

The quantities to display are debatable (e.g. maybe min of all the individual elements’ ESS, max of the Rhats, etc), so it would be good to get input from Andrew and anyone else interested.

Research direction

Start by reading discussion #32 and the existing summary objects and custom print method mentioned in the issue. Clarify which quantities should represent vector, matrix, and array parameters, then define what done means: a summary with one line per named parameter and agreed output values.
