Time‐Varying Treatment Effect Models in Stepped‐Wedge Cluster‐Randomized Trials With Multiple Interventions

Statistics in Medicine, Volume 45, Issue 13-14, June 2026.
ABSTRACT The traditional model specification of stepped‐wedge cluster‐randomized trials assumes a homogeneous treatment effect across time while adjusting for fixed‐time effects. However, when treatment effects vary over time, the constant effect estimator may be biased.

Variance‐Guided Regression for Heteroscedastic Data With a Grouping‐Based Extension for Nonlinear Prediction

Statistics in Medicine, Volume 45, Issue 13-14, June 2026.
ABSTRACT Although homoscedasticity is often assumed in linear regression, real data may show variance patterns or residual structures that violate this assumption. We propose VarGuid, a variance‐guided framework for two related settings: Covariate‐dependent conditional variance under a global linear mean model, and residual nonlinear mean structure ...

Abunmix enables the simple and robust multiplexed immunofluorescence imaging

VIEW, Volume 7, Issue 3, June 2026.
Multiplexed fluorescence imaging is limited by bleed‐through signals arising from the use of antibodies derived from the same host species. Abunmix can separate signals from multiple antibodies generated from the same host species using a signal unmixing algorithm.

Simultaneously Modelling Occurrence and Quantity of Multivariate Semicontinuous Data

Australian &New Zealand Journal of Statistics, Volume 68, Issue 2, June 2026.
ABSTRACT Joint models have been developed recently for multivariate semicontinuous data; however, joint modelling implies structured covariance and nonnegative correlation among responses, and thus is inflexible in accommodating complex covariance structures in practice.
