Regression analysis with partially labelled regressors: carbon dating of the Shroud of Turin

  author={Marco Riani and Anthony Curtis Atkinson and Giulio Fanti and Fabio Crosilla},
  journal={Statistics and Computing},
The twelve results from the 1988 radio carbon dating of the Shroud of Turin show surprising heterogeneity. We try to explain this lack of homogeneity by regression on spatial coordinates. 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. Plots of robust regression residuals… 

Statistical and Proactive Analysis of an Inter-Laboratory Comparison: The Radiocarbon Dating of the Shroud of Turin

These analyses suggest that the 1988 radiocarbon dating does not match the current accuracy requirements and it would be interesting to know the accurate age of the Shroud of Turin.

Radiocarbon Dating of the Turin Shroud: New Evidence from Raw Data

In 1988, three laboratories performed a radiocarbon analysis of the Turin Shroud. The results, which were centralized by the British Museum and published in Nature in 1989, provided ‘ conclusive

X-ray Dating of a Turin Shroud’s Linen Sample

On a sample of the Turin Shroud (TS), we applied a new method for dating ancient linen threads by inspecting their structural degradation by means of Wide-Angle X-ray Scattering (WAXS). The X-ray

The Shroud of Turin: A Historiographical Approach

Criteria of historical assessment are applied to the Turin Shroud to determine which hypothesis relating to the image formation process is the most likely. To implement this, a ‘Minimal Facts’

RETRACTED ARTICLE: Is the Shroud of Turin in relation to the Old Jerusalem historical earthquake?

Phillips and Hedges suggested, in the scientific magazine Nature (1989), that neutron radiation could be liable of a wrong radiocarbon dating, while proton radiation could be responsible of the

Uncovering the sources of DNA found on the Turin Shroud

The analyses detected sequences from multiple subjects of different ethnic origins, which clustered into a number of Western Eurasian haplogroups, including some known to be typical of Western Europe, the Near East, the Arabian Peninsula and the Indian sub-continent.

A comparison of robust methods with small sample experimental data

The goal of this work is to compare alternative approaches to robust regression estimation in a small sample situation, where asymptotics become of very little help.

Monte Carlo method applied to the mechanical dating of the Turin Shroud

Alternative dating methods to radiocarbon have been recently developed to study the Turin Shroud (TS), the linen sheet that according to the tradition enveloped the dead body of Jesus Christ; among

Mechanical ond opto-chemical dating of the Turin Shroud

The TS (Turin Shroud) is a linen cloth which enveloped the dead body of a tortured and crucified man that is believed by many to be the burial cloth of Jesus Christ. The linen fabric has been



Investigating a Dated Piece of the Shroud of Turin

We present a photomicrographic investigation of a sample of the Shroud of Turin, split from one used in the radiocarbon dating study of 1988 at Arizona. In contrast to other reports on


The use of a similar approach for other kinds of correlated offset (such as overall measurement bias or regional offsets in the calibration curve) is discussed and the implementation of these methods in OxCal v 4.0 is presented.

Dealing with Outliers and Offsets in Radiocarbon Dating

The wide availability of precise radiocarbon dates has allowed researchers in a number of disciplines to address chronological questions at a resolution which was not possible 10 or 20 years ago. The

Formal Statistical Models for Estimating Radiocarbon Calibration Curves

We report on the development and implementation of a model-based statistical method for the estimation of radiocarbon calibration curves using diverse data. The method takes account of uncertainty on

A New Robust Statistical Model for Radiocarbon Data

The general method currently used to analyze radiocarbon data (y) is conditional on the standard deviation (σ), reported by 14C laboratories, which reflects the uncertainty in the dating process.

Intcal04 Terrestrial Radiocarbon Age Calibration, 0–26 Cal Kyr BP

A new calibration curve for the conversion of radiocarbon ages to calibrated (cal) ages has been constructed and internationally ratified to replace IntCal98, which extended from 0–24 cal kyr BP

Summarizing a Set of Radiocarbon Determinations: A Robust Approach

A general (Bayesian) method for summarizing sets of radiocarbon determinations is presented, combining archaeological a priori considerations with the radiocarbon determinations to obtain dates on

The forward search: theory and data analysis

Least Median of Squares Regression

Abstract Classical least squares regression consists of minimizing the sum of the squared residuals. Many authors have produced more robust versions of this estimator by replacing the square by

Robust Diagnostic Regression Analysis

Interestingly, robust diagnostic regression analysis that you really wait for now is coming. It's significant to wait for the representative and beneficial books to read. Every book that is provided
