One of my New Year's resolutions was to be more active on social media again. Why not begin telling my tiny audience about my R package that was recently accepted to CRAN? The goal of `ivd` is to facilitate random effects selection with a spike-and-slab prior on the scale part of MELSMs.

Researchers study long developmental spans using accelerated longitudinal designs (ALDs). Fitting parametric growth or change score models imposes strong assumptions. We use functional data analysis to nonparametrically model ALDs in continuous time. Check out the preprint: osf.io/preprints/ps...

Announcement: I am excited to be co-editing (with Li Cai) an upcoming Special Issue of the Journal of Mathematical Psychology on "Advances in Statistical Model Evaluation." Proposals due Feb 1. Details: www.sciencedirect.com/special-issu... Please repost! #quantpsych #mathpsych #philsci #statsky

Advances in Statistical Model Evaluation
Submission deadline: 31 December 2026
The Special Issue accepts theoretical, methodological, applied, and philosophically oriented research on frequentist, Bayesian, and information-theoretic advances in statistical model evaluation.

Topics of interest for this call for papers include but are not restricted to:

• Methodological advances in fit assessment, parametric bootstrapping, cross-validation, and/or other frequentist model evaluation methods

• Methodological advances in prior and/or posterior predictive model checking, specification and use of informed priors, Bayes factors, and/or other Bayesian model evaluation

• Methodological advances in minimum description length, normalized maximum likelihood, and/or other information-theoretic model evaluation methods

• Practical applications and tutorials of advanced model evaluation methods

• Philosophy of science issues underlying statistical model evaluation

• Critiques/perspectives/commentaries on statistical model evaluation

Amazing collection of resources in the replies! I'm really glad that the academic 'twitter' is still alive here and that I decided to get back to social media :)
