Sentences with phrase «calendar age uncertainty»

The two posterior PDFs in Figure 2 imply very different calendar age uncertainty ranges.

Not exact matches

So in both cases, one can construct a confidence / credible interval for the carbon - 14 age by well - known methods (that exhibit perfect probability matching), and then simply transform the endpoints of this interval to calendar years using the calibration curve (which I'll assume is known exactly, since uncertainty in it doesn't seem to really affect the argument).

However, I'm not convinced that his treatment of calibration curve uncertainty is noninformative even in the absence of it varying with calendar age.

Initially I was concerned that the non-monotonicity problem was exacerbated by the existence of calibration curve error, which results in uncertainty in the derivative of 14C age with respect to calendar age and hence in Jeffreys» prior.

An error - free laboratory measurement of modern fraction does not imply that the problem collapses into a deterministic look - up from the calibration curve — even if the curve is monotonic over the relevant calendar interval — because the curve itself carries uncertainty in the form of the variance related to the conditional probability of RC age for a given calendar date.
