IncAAM: Bayesian Age-at-Maturity Analysis from Increment-Width Growth Series

Bayesian hierarchical nonlinear mixed-effects analysis for estimating age at sexual maturity from annual increment-width growth series. The method estimates age at maturity using tangent-ratio and jerk approaches, including the hierarchical population-median tangent-ratio estimate and an analytical posterior crossing ogive with Bayesian credible intervals and estimated A50. Methodological details and applications are described in Campana, Smoliński, Morrongiello and Black (2027, in press).
