Dealing outliers offsets radiocarbon dating
Plots of robust regression residuals from the forward search indicate that some sets of allocations are implausible.We establish the existence of a trend in the results and suggest how better experimental design would have enabled stronger conclusions to have been drawn from this multi-centre experiment.
Whilst by no means complete, a historical framework can be constructed for the full length of ancient Egyptian civilization.
However, although the locations of the samples sent to the three laboratories involved are known, the locations of the 12 subsamples within these samples are not.
We consider all 387,072 plausible spatial allocations and analyse the resulting distributions of statistics.
Green indicates presence of sapwood, black indicates that pith or last ring under the bark is present. Hd = Heidelberg; MAMS = Curt-Engelhorn-Zentrum Archaeometrie.
C data and placement of the 10-year tree-ring samples (mid-points) within the 213-year chronology.
Search for dealing outliers offsets radiocarbon dating:
The twelve results from the 1988 radio carbon dating of the Shroud of Turin show surprising heterogeneity.
