Radiocarbon dating calibration oxcal Xxx lifecam

In 1962, Martin Aitken organized a day meeting for archaeologists who had purchased proton magnetometers, which became an annual meeting.

The scope of the meetings broadened in 1969 to become the “Symposium on Archaeometry and Archaeological Prospection”, held in Oxford until 1975.

The first volume of the journal (a word coined by Christopher Hawkes) was published in 1958, originally subtitled the ‘Bulletin of the Research Laboratory for Archaeology and the History of Art, Oxford University’, but including international contributions from volume 3 onwards.

This is still published for Oxford University by Wiley-Blackwell.

In other words, when estimating the value of a fixed but unknown parameter, does the true value lie outside the specified uncertainty range in the indicated proportion of cases?

This so-called frequentist coverage or probability-matching property can be tested by drawing samples at random from the relevant uncertainty distributions.

I also commented, saying if one assumes a uniform prior for the true calendar date, then Doug Keenan’s results do not follow from standard Bayesian theory.

Although the Ox Cal and Calib calibration graphs (and the Calib manual) are confusing on the point, Bronk Ramsey’s papers make clear he does use such a uniform prior.

Dates between 50.000 and 1 BP will be calibrated using the calibration curve Cal Pal2007_HULU.

Use of what are, in my view, unsatisfactory methods remains common.

Fortunately, regardless of foundational disagreements I think most people (and certainly most scientists) are in practice prepared to judge the appropriateness of statistical estimation methods by how well they perform upon repeated use.
