Reframing Three-Dimensional Morphometrics Through Functional Data Innovations
Aneesha Balachandran Pillay, Issa-Mbenard Dabo, Sophie Dabo-Niang +1
This study innovates geometric morphometrics by incorporating functional data analysis, the square-root velocity function (SRVF), and arc-length parameterisation for 3D morphometri…
Functional regression with randomized signatures: An application to age-specific mortality rates
Zhong Jing Yap, Dharini Pathmanathan, Sophie Dabo-Niang
We propose a novel extension of the Hyndman-Ullah (HU) model to forecast mortality rates by integrating randomized signatures, referred to as the HU model with randomized signature…
Compositional data analysis for modelling and forecasting mortality using the α-transformation
Han Ying Lim, Dharini Pathmanathan, Sophie Dabo-Niang
Mortality forecasting is crucial for demographic planning and actuarial studies, especially for projecting population ageing and longevity risk. Classical approaches largely rely o…
