Gotcha. It is the headlines that count.
1. I appreciate professor deLeuw recommending A. W. F.
Edward's book "Likelihood" (expanded version). Read it from cover to cover.
Excellent source of ideas and analysis of Fisher's contributions.
2. The issue is, do we follow the maximum likelihood

I would like to enter the arena.
I see the original question as two questions, one about
probability in a general sense, and the second about probability as used within
Bayes Theorem. This is in line with the historical arguments.

Skewness is only well defined for univariate distributions.
The Johnson SU distribution approximation for the skewness distribution converts
a Pearson skewness measure to a normal distribution Z value. As with all large
data sets, a small skewness will show up as indicationg that the departur
