In order to avoid having to make a start on examination marking I was having a trawl through the arXiv this morning when I found an interesting paper by Stephens & Gleiser called An Informational Approach to Cosmological Parameter Estimation. The abstract is:

You can download a PDF of the full paper here.

I haven’t had time to go through the manuscript in detail but while it doesn’t seem to say very much of a specific nature about the Hubble constant tension issue, it does introduce an approach which is new to me. The Jensen-Shannon Divergence is a variation on the familiar Kullback-Leibler Divergence.

Anyway, I’d be interested in comments on this from experts!
