Fooled by the normalization method and some narrow rings

Postby Lars-Ake » 13 Apr 2009, 15:32

While analyzing the data in the file CO20050101-LCE-AjC.txt at the French CNRS database I observed a number of quite high Baillie/Pilcher and Hollstein based TTest correlation values which were not considered as correct datings. An analysis revealed that it was caused by a combination of VERY narrow rings and a weakness in these normalization methods. It is all described under the heading "Methodology" and "Fooled by narrow rings..." at
