IDADE2

IDADE2 estimates adult age-at-death from human skeletal remains by applying Bayesian inference to acetabular scores.

Key Features:

• Bayesian Inference: Applies Bayesian statistical methods to model age-related changes in the acetabulum and produce probabilistic age estimates.
• Probabilistic Output: Reports age ranges with associated probabilities for inferred ages.
• Reference Datasets: Uses documented skeletal reference collections from Spain (24 females, 52 males), Portugal (317 females, 294 males), and the United States (370 females, 456 males).
• Implementation: Implemented in R.
• Estimation Modes (Option 1 and Option 2): Option 1 estimates individual age-at-death using reference acetabular scores; Option 2 accepts user-supplied reference and test collections or alternative age markers and methods.

Scientific Applications:

• Forensic Anthropology: Age-at-death estimation for forensic casework involving single individuals using acetabular scoring and Bayesian methods.
• Bioarchaeology: Population-level analyses of age distributions and demographic profiles in large skeletal samples.

Methodology:

Employs Bayesian statistical inference on acetabular scoring to generate probabilistic age ranges; uses documented reference skeletal datasets from Spain (24F/52M), Portugal (317F/294M), and the United States (370F/456M); implemented in R; provides two operational modes—Option 1 for individual age estimation using reference acetabular scores and Option 2 for analyses using custom reference/test collections or alternative age markers and methods.
