While on the subject of mechanical methods of statistical research I
can't
resist quoting Doob's (1997) Statistical Science interview:

The relevance to the present inquiry is confirmed by the misspelling
of Dennison in the Annals reference
quoted below. See, for example:
http://www.amazon.com/Avery-Dennison-Metal-Rim-Tags/dp/B000AN376G
On the substance of Jean's question, Mark's interpretation seems very
plausible.
Thanks to Jean and to Martin Maechler for adding this dataset to R.
