Family research in child and adolescent mental health has often been framed as if influence runs mainly from adults to children. In this #OpenAccess JCPP Advances Editorial, @eivindy.bsky.social comments on when children also shape the family environment. https://bit.ly/4f3FjyS

Scientists should be judged not just on their research, but the claims they make. Quitting smoking is one of the most powerful ways you can improve your health. Visiting a museum can never come close. Such a claim should require extraordinary evidence. This study is anything but. 18/18 🧵

BGA needs people to communicate if their not going to back out/cancel last minute, or will only be present on 1/2 days, so they can allocate spots to our colleagues and friends who otherwise currently cannot attend due to venue capacity.

Behavior Genetics Association@behaviorgenetic.bsky.social · 5mo ago

⚠️ This BGA has turned out to be exceptionally popular with unprecedented numbers of submissions and people wanting to attend. We are now holding a waiting list for non-speakers (this includes symposia Chairs and Discussants) who have not yet registered.

I've made an R package for Bayesian Rasch #psychometrics with brms models, easyRaschBayes (on CRAN), implementing simple functions to create figures and tables with model fit metrics, etc. Attaching figures from conditional item infit, item-restscore with GK gamma, and the log-likelihood criterion.

as I'm revising my course materials, I keep stumbling upon cool @mc-stan.org developments. Current favorites: 1. your model has funnels and you exhausted reparametrization ideas: metric = "dense_e" makes your HMC learn about covariance btw parameters. Sloooow, but effective! 1/

In 2021 we reported that live learning outperformed recorded learning. In a new preregistered analysis, my first senior-author paper led by Stan de Visser (pre-print), we find that this benefit does not increase with interactivity. The potential to interact may be enough to boost learning. A thread:

This is really neat. I have borrowed the reliability() function to my `easyRasch` package, and use plausible values instead of fully Bayesian estimation to produce similar estimates/CIs, see code example below. RMU point estimates are similar to EAP reliability. pgmj.github.io/easyRasch/re...

New preprint with @rogierk.bsky.social @paulbuerkner.com - we introduce "relative measurement uncertainty" - a reliability estimation method that's applicable across a broad class of Bayesian measurement models (e.g., generative-, computational- and item response theory-models osf.io/h54k8

I've added a new example to our paper's repo, demonstrating how our reliability method replicates Cronbach's alpha for a simple model, but also how our method can account for: (i) binary data, (ii) varying numbers of items per pps, & (iii) improvement over trials www.bignardi.co.uk/8_bayes_reli...
