Rank‐based estimation of propensity score weights via subclassification

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Propensity score (PS) weighting estimators are widely used for causal effect estimation and enjoy desirable theoretical properties, such as consistency and potential efficiency under correct model specification. However, their performance can degrade in practice due to sensitivity to PS model misspecification.

Bayesian clustering of multivariate extremes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The asymptotic dependence structure between multivariate extreme values is fully characterized by their projections on the unit simplex. Under mild conditions, the only constraint on the resulting distributions is that their marginal means must be equal, which results in a nonparametric model that can be difficult to use in applications ...

Pigment‐Macromolecule Complexes Isolation from Sea Urchin Biomineral Waste for Coloring Materials

open access: yesChemistry–Methods, EarlyView.
A methodology has been developed to extract the colored organic fraction occluded within seashell biomineral waste. Applied to sea urchin skeletons, free polyhydroxylated naphthoquinone (PHNQ) pigments and PHNQ‐macromolecule complexes are isolated. These complexes show superior pH stability in purple hues compared to free PHNQ, which shifts from red to
