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!
