Just curious if anyone has ever tried shinylive at the same time as webexercises and whether the two play nicely with each other? #rstats #rshiny #shinylive

While teaching a course on Item Response Theory this semester, I created a Shiny app for visualizing some polytomous item response models: falkcarl.shinyapps.io/polytomous/ This is an initial draft, so comments/questions/suggestions are welcome! #Psychometrics #RShiny #IRT

Now I'm also looking for a research software engineer to implement a pile of research results to R packages loo, posterior, bayesplot, projpred, priorsense, brms or/and Python packages ArviZ, Bambi and Kulprit. Apply by email with no specific deadline (see contact info at users.aalto.fi/~ave/)

FYI. The House of Commons committee where this went down also records the meetings: www.ourcommons.ca/Committees/e...

I'm now also looking for a postdoc with strong Bayesian background and interest in developing Bayesian cross-validation theory, methods and software. Apply by email with no specific deadline (see contact information at users.aalto.fi/~ave/). Others, please share

When there is a random way to do something, there is a less random way that is better but requires more thought. In this case, regression models that make no sense don't belong in a multiverse analysis. An inferential regression without a causal justification is like an opinion without reasons.

Anyone else using #shinylive with #rstats having trouble getting nice plotting packages like #ggplot2 or #plotly to work? Curious what work arounds there are. Many thanks! ( #shiny works fine)

Join us as we explore our options, tomorrow….

There is still time to submit a proposal to host IMPS 2028! Visit www.psychometricsociety.org/hosting-oppo... for details. #QuantitativePsychology #Psychometrics

I clearly had a lot of thoughts/feelings from reading Terry's blog post, so I wrote one of my own It ended up being a bit of a stream-of-thought post but I think it captures some of my worries benharrap.com/post/2025-10... #statssky #episky #academicsky

Would sure be funny to embed certain keyword combinations into assignments to mess with cheating students who then copy the questions into an LLM prompt.

Does anyone else accidentally click on reactions to emails on #Outlook for Office 365? Why can I react to emails? 🎉

Excited to announce that our paper with @pingfanhu.bsky.social and Bogdan Bunea on our #rstats package {surveydown} is now published in @plosone.org The paper compares the benefits of using a code-based approach to survey design, leveraging #quarto and #shiny journals.plos.org/plosone/arti...

The University of Central Florida College of Medicine is looking to hire a Psychometrician (Assistant or Associate Professor of Medicine). Learn more: www.click2apply.net/OJJDagiDEDql... #NCMECareers

I'd also be curious to know what people use

Bridge sampling estimates marginal likelihood. A recommendation has been to use an order of magnitude more posterior draws than otherwise. With Giorgio Micaletto we show how to compute MCSE for bridge sampling to decide how many draws are actually needed arxiv.org/abs/2508.14487

Considering EBICglasso for network modeling, but have a lot of missing data? A recent paper (accepted at Multivariate Behavioral Research), osf.io/preprints/os... may help. The paper is a bit technical, so a new blog post focuses on software: www.psych.mcgill.ca/perpg/fac/fa... #rstats #quantpsych

This is the definition of a failed social media platform.

My dept at the University of Auckland (NZ) will be hiring in social psych at the junior level this cycle. Official ad to follow It's a big research-active dept with fun colleagues, plus you can commute to uni on a boat, paired with a pleasant walk thru Albert Park (this pic from heading home today)

Mark your calendars: IMPS 2026 will be at Yonsei University in Seoul, Republic of Korea, from July 21-24, with short courses on July 20. Updates will be posted to the conference website: www.psychometricsociety.org/imps-2026 #IMPS2026 #Psychometrics #QuantitativePsychology

Happy to announce ✨quarto-revealjs-editable✨ This fully supersedes the imagemover extension, as I back then didn't realize the potential. You can now also move, resize, change font size and alignment for text in your slides github.com/EmilHvitfeld... #quarto #slidecrafting

Now on CRAN, ggdiagram is a #ggplot2 extension that draws diagrams programmatically in #Rstats. Allows for precise control in how objects, labels, and equations are placed in relation to each other. wjschne.github.io/ggdiagram/ar...

I've written a short blog post about the process of switching my personal website from Hugo to Quarto, some of the tricky things, and advice for those thinking about doing the same! Link: nrennie.rbind.io/blog/hugo-qu... #RStats #QuartoPub

If you do survey research with Likert-type items and worry about random responders, Michael John Ilagan & I made a Shiny app we think some of you may like. falkcarl.shinyapps.io/BotApp1/ #SurveyResearch #DataQuality #Psychometrics #OnlineSurveys #SurveyBots #RandomResponders #rstats #Shiny

How do researchers detect random responders or survey bots these days? I am interested in knowing what approaches are used. On Bluesky, I have seen work by @dr-ashley-brooks.bsky.social (osf.io/za8v6_v1) and from @sara-suzuki.com‬ about Prolific people failing Qualtrics scores...
