Probabilistic weighted Dirichlet process mixture with an application to stochastic volatility models

Canadian Journal of Statistics, EarlyView.
Abstract In this article, we propose a flexible Bayesian modelling framework and investigate the probabilistic weighted Dirichlet process mixture (pWDPM). The construction and properties of a probabilistic weight function are illustrated. The advantage of the pWDPM under the log‐squared transformed stochastic volatility (SV) model is demonstrated.

A parameter transformation of the anisotropic Matérn covariance function

Canadian Journal of Statistics, EarlyView.
Abstract We describe a polar coordinate transformation of the anisotropy parameters of the Matérn covariance function, which provides two benefits over the standard parameterization. First, it identifies a single point (the origin) with the special case of isotropy.

Noisy matrix completion for longitudinal data with subject‐ and time‐specific covariates

Canadian Journal of Statistics, EarlyView.
Abstract In this article, we consider the imputation of missing responses in a longitudinal dataset via matrix completion. We propose a fixed‐effect, longitudinal, low‐rank model that incorporates both subject‐specific and time‐specific covariates. To solve the optimization problem, a two‐step optimization algorithm is proposed, which provides good ...

A Systematic Review of the Costs of Drug‐Associated Acute Kidney Injury and Potential Cost Savings With Nephrotoxin Stewardship Prevention Strategies

Clinical Pharmacology &Therapeutics, Volume 117, Issue 4, Page 989-1004, April 2025.
There is a scarcity of information related to the financial impact of acute kidney injury (AKI), and even more so the economics of drug‐associated AKI (D‐AKI). Our goal was to provide a comprehensive summary of the economic burden of D‐AKI by evaluating the costs of D‐AKI compared to not developing AKI and cost savings associated with nephrotoxin ...
