TL;DR: In this paper, the authors outline the background to the optical dating program at Jinmium, and describe the experimental design and statistical methods used to obtain optical ages from single grains of quartz sand.

TL;DR: In this paper, finite mixtures and two new infinite mixture models were proposed to estimate various features of interest such as the minimum age, the other component ages and the age dispersion.

TL;DR: In this article, the statistical estimation of uncertainties and variation for comparing and interpreting age estimates, with specific reference to the estimation of equivalent dose (De) values in the optically stimulated luminescence (OSL) dating of sediments.

TL;DR: In this article, the problem of estimating the component ages of a sample containing grains of different true ages was considered and formulae for estimating these parameters along with their relative standard errors, confidence intervals and appropriate diagnostics when the grains are dated by the external detector method.

TL;DR: Age ages for nine sites from varied climatic and ecological zones across southern Africa show that both industries were short-lived (5000 years or less), separated by about 7000 years, and coeval with genetic estimates of population expansion and exit times.
