Simulate radiocarbon dating

In this way, a time series is constructed that contains information about trends in the frequency of radiocarbon dates, which in turn becomes interpreted as a proxy measurement of past levels of activity.As many authors have pointed out, using the technique uncritically and as a direct proxy is applicable only to broad trends in very large datasets (Chiverrell et al. This is because the inherently statistical nature of radiocarbon measurements, together with the non-Gaussian uncertainty introduced by the calibration process, causes artefacts in the resulting curve that could be misinterpreted as “signal” but are, in fact, “noise”.To do it, a portion of the calibration dataset or “curve” is selected and used as parameters in the standard equation that describes the probability density of the normal distribution (or alternatively, the distribution).The resulting set of numbers is usually normalised so that the numerical values correspond to the correct boundary conditions of the probability density function of the “date”.Defence of the technique has been maintained by many authors, however, as cumulative probability distributions can be seen as a useful way to explore trends in data aggregated from different sites, both in terms of environmental history ().

In this brave new world, many archaeologists and their collaborators have developed novel methods and theories dealing with the rather complex and intertwined issues of meaningfully summarizing large datasets, but also accounting for the chronological uncertainty and sampling bias inherent to archaeological research.There is no universal solution or consensus; the heuristic of 200 years suggested by ) as a natural limit to the present resolution of radiocarbon data trends is sufficient for long-term research in prehistoric archaeology, but unlikely to be sufficient for protohistoric work, for example, where changes of less than 100 years are typically of interest.Even in prehistory, the success of Bayesian chronologies in examining individual sites or certain cultural developments has transformed expectations of how much precision to expect from radiocarbon data.The ground-breaking nature of much of this effort has led to solutions that are somewhat experimental in nature, often tailored to individual problems, or informed by quite rigid theoretical assumptions.These factors hamper their universal applicability, and, to date, only a small number of platforms for dealing with archaeological-chronological data have been widely adopted ().
