Luminescence dating, single-grain dose distribution

The graphical display of single-grain or single-aliquot equivalent dose values can be accomplished in various ways, of which the radial plot provides an effective means of assessing all of the salient information at a glance. After an initial visual inspection of the distribution, one or more statistical "age models" can be used to estimate the equivalent dose for the population of grains (or aliquots) related most closely to the event of interest. Such models should be supported by well-established statistical theory, but the choice of model depends fundamentally on the scientific context of each sample and on the purpose of the investigation.
