Rank‐based estimation of propensity score weights via subclassification
Canadian 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.

A class of directed acyclic graphs with mixed data types in mediation analysis
Canadian Journal of Statistics, EarlyView.Abstract We propose a unified class of generalized structural equation models (GSEMs) with data of mixed types in mediation analysis, including continuous, categorical, and count variables. Such models extend substantially the classical linear structural equation model to accommodate many data types arising from the application of mediation analysis ...

Robust multitask feature learning with adaptive Huber regressions
Canadian Journal of Statistics, EarlyView.Abstract When data from multiple tasks have outlier contamination, existing multitask learning methods perform less efficiently. To address this issue, we propose a robust multitask feature learning method by combining the adaptive Huber regression tasks with mixed regularization. The robustification parameters can be chosen to adapt to the sample size,

Predicting cervical cancer DNA methylation from genetic data using multivariate CMMP
Canadian Journal of Statistics, EarlyView.Abstract Epigenetic modifications link the environment to gene expression and play a crucial role in tumour development. DNA methylation, in particular, is gaining attention in cancer research, including cervical cancer, the focus of this study.

Annals of the Child Neurology Society, EarlyView.ABSTRACT Objective Walking capacity declines prematurely in individuals with ataxia telangiectasia. However, granular data on walking capacity loss in ataxia telangiectasia are scarce. In this large cross‐sectional cohort, we describe age‐related walking capacity loss reported by participants and compare categories of a subjective walking capacity ...

Clinical Pharmacology in Drug Development, EarlyView.Abstract Zanubrutinib is a next‐generation Bruton tyrosine kinase inhibitor approved for treating B‐cell malignancies. Two phase 1 studies evaluated a new 160‐mg zanubrutinib tablet versus 80‐mg capsules. In study BGB‐3111‐115 (n = 43), a randomized 3‐period crossover trial, relative bioavailability and food effects were assessed.
