Age at death was obtained using Bayesian inference and a computational application (IDADE2) that requires a reference population, close in geographic and temporal distribution to the target case, to calibrate age ranges from scores generated by the technique. The inaccuracy of this method is 8 years. The direction of bias indicates the acetabulum technique tends to underestimate age. The categories 46-65 and 76-90 years exhibit the smallest inaccuracy (0.2), suggesting that this method may be appropriate for individuals over 40 years. Eighty-three percent of age estimates were +/- 12 years of known age; 79 percent were +/- 10 years of known age; and 62 percent were +/- 5 years of known age. Identifying a suitable reference population is the most significant limitation of this technique for forensic applications. (Published Abstract)
