I've used Lavaan almost every (work)day for 15 years, but this open source labour of love has never received proper institutional support. I'm delighted to be a small part of an 1.5M OpenScienceNL award, led by Jorgensen, to completely revamp and futureproof Lavaan www.openscience.nl/en/news/45-p...

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:

Happy to share my new paper published in @nathumbehav.nature.com: A critical look at statistical power in computational modeling studies, particularly those based on model selection. www.nature.com/articles/s41...

We wrote an article explaining why you shouldn't put several variables into a regression model and report which are statistically significant - even as exploratory research. bmjmedicine.bmj.com/content/4/1/.... How did we do?

New paper by brilliant final yer PhD student Blanca Piera Pi-Sunyer and colleagues, including 3 undergraduate students (Evans, Ratcliffe, Janaarthanan) 🤩 The Relationship between Perceived Friendship Quality and Self-Judgements in Adolescent Girls from London journals.sagepub.com/doi/epub/10....

Blanca Piera Pi-Sunyer on how to make the world a better place for young people, the cumulative impact of adversity & how to mitigate it in the Gates Cambridge podcast, So, now what? - @cambridgeuni.bsky.social

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...

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...

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

Our approach to understanding how adversities impact adolescent development often neglects the specificity and complexity of adolescence. In our new review, we propose the adolescent adverse experiences framework to capture adverse experiences at multiple levels: www.nature.com/articles/s41...

Another excellent evaluation of the Sure Start programme, this time on its effects on youth offending. Once again it shows that investment in early years, preventative services improves life chances, reduces the costs of social failure and delivers major benefits.
