Influence of <sup>14</sup>C Concentration Changes in the Past On Statistical Inference of Time Intervals

Adam Michczyński-2004-01-01-Radiocarbon

TL;DRAbstract

The influence of the calibration curve on the statistical inference of time intervals was investigated. For this purpose, the calculation of the summed probability density function was used. Computer simulations were done for batches of 11 samples, each time uniformly covering 200-yr time intervals. The results show that the calibration curve causes the summed probability density function of a group to cover a wider interval than the real-time interval of the phenomenon. Moreover, the estimated time interval may be often shifted in relation to the real-time interval.
