Variable Selection for Fixed and Random Effects in Multilevel Functional Mixed Effects Models
Statistics in Medicine, Volume 45, Issue 18-19, August 2026.ABSTRACT We develop a new method for simultaneously selecting fixed and random effects in a multilevel functional regression model. The proposed method is motivated by accelerometer‐derived physical activity data from the 2011 to 2012 cohort of the National Health and Nutrition Examination Survey (NHANES), with the aim of identifying age and race ...

Statistics in Medicine, Volume 45, Issue 18-19, August 2026.ABSTRACT Frequent visits in cohort studies are important as they enable, among others, the assessment of disease progression and treatment effectiveness. In HIV studies, extended intervals between visits have been shown to be associated with adverse outcomes (e.g., antiretroviral therapy interruption).

Examining the clustering of lifestyle factors and affect in daily life: An idiographic approach
Applied Psychology: Health and Well-Being, Volume 18, Issue 4, August 2026.Abstract There has been an increase in interest in the health and well‐being benefits of lifestyle factors such as physical activity, diet, sleep, and social interaction. Previous research has highlighted how lifestyle factors, both healthy and unhealthy, tend to covary or cluster together.

An Uncertainty Based Approach for Dealing With Selection Bias in Non‐Probability Samples
International Statistical Review, Volume 94, Issue 2, Page 264-290, August 2026.Summary The main issue with non‐probability samples is that the standard design‐based approach cannot be applied as the selection mechanism is unknown. In this paper, the concept of uncertainty on data generating model, resulting from the lack of knowledge of the sampling design acting in the non‐probability sample, is discussed.
