Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.

Residual permutation tests for feature importance in machine learning

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological research has traditionally relied on linear models to test scientific hypotheses. However, the emergence of machine learning (ML) algorithms has opened new opportunities for exploring variable relationships beyond linear constraints.

From tetrachoric to kappa: How to assess reliability on binary scales

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Reliability is crucial in psychometrics, reflecting the extent to which a measurement instrument can discriminate between individuals or items. While classical test theory and intraclass correlation coefficients are well‐established for quantitative scales, estimating reliability for binary outcomes presents unique challenges due to their ...

Bayesian inference for dynamic Q matrices and attribute trajectories in hidden Markov diagnostic classification models

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Hidden Markov diagnostic classification models capture how students' cognitive attributes evolve over time. This paper introduces a Bayesian Markov chain Monte Carlo algorithm for diagnostic classification models that jointly estimates time‐varying Q matrices, latent attributes, item parameters, attribute class proportions and transition ...

Concerted Cultivation in Canada: Class‐Based Approaches to Parenting

open access: yesCanadian Review of Sociology/Revue canadienne de sociologie, EarlyView.
ABSTRACT The literature on concerted cultivation describes how higher‐class parents reproduce their social class standing in their children by engaging in ‘cultivating’ parenting practices. I use Latent Class Analysis and multinomial logistic regression applied to survey data from Canada to inductively uncover distinct approaches to parenting and then ...

Oral Health and Social Isolation After 6 Years: Mediation of Oral Functions

open access: yesCommunity Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives Tooth loss was longitudinally associated with social isolation. The absence of dental prosthesis use was an additional risk factor. However, the mediating pathways for this association are unknown. The aim of this cohort study was to estimate the mediating effect of three oral functions: speaking, smiling and chewing observed at ...
