Very excited to host two events in Singapore: the professional certification workshops on Network Psychometrics in Decemer and the 2026 edition of the Australasian Mathematical Psychology conference in February! Links for registration below. fass.nus.edu.sg/psy/network-... ampc2026.com

Welcome to the world Luna! And happy birthday to your big brother turning 4 already ❤️

Happy to share that our article, led by @xinkaidu.bsky.social, on confirmatory network modeling has been published in Psychological Methods! psycnet.apa.org/record/2026-...

Save the date! Next year we will host the 2026 Australasian Mathematical Psychology Conference in Singapore! Including research in mathematical psychology, computational modeling, psychometrics and data science / AI! #AMPC26SG

I uploaded some #Rstats tutorial videos on ggplot2, tidyr and dplyr: www.youtube.com/playlist?lis...

Very honored to be among the new APS Fellows! www.psychologicalscience.org/members/fell...

🚀 New Article Alert! "Observed correlations between person-means depend on within-person correlations" By Jonas Haslbeck (@jmbh.bsky.social) & Sacha Epskamp (@sachaepskamp.bsky.social) advances.in/psychology/1...

I gave a 2-hour workshop on Structural Equation Modeling and Confirmatory Factor Analysis in lavaan for the Psych #rstats Club. the recording is available here: youtu.be/YrxvV8zlNLY?... Supported by @improvingpsych.org!

Super excited today to teach the first summer school / workshop on longitudinal network modeling in Singapore and to receive the first ever translation (in Japanese!) of our textbook!

Did anyone check if the #Paris2024 Olympics mascot follows a normal density?

Updated preprint on potential bias in mlVAR between-person network results! osf.io/preprints/ps...

Two more weeks to register for our workshops on network psychometrics and longitudinal data modeling in Singapore next month! Registration closes July 15. fass.nus.edu.sg/psy/network-...

Very excited to teach the first ever workshop on psychonetrics at the Modern Modeling Methods (M3) conference in Storrs, Connecticut today! All materials are now available on the OSF: osf.io/dax8g/

Just in time for the Modern Modeling Methods (M3) conference starting this Monday (modeling.uconn.edu), #Rstats 📦 psychonetrics version 0.13 is now on CRAN! This version (finally) includes bootstrap methods for accuracy and stability checks.

Interested in Network Psychometrics? This summer there are workshops in three different continents! June 24 (US): modeling.uconn.edu July 1 - July 4 (Netherlands): psychosystems.org/psynets-work... July 29 - August 3 (Singapore): fass.nus.edu.sg/psy/network-...

Just in time for #aps24sf, the psychonetrics #Rstats package for (dynamic) SEM and network psychometrics has been updated to version 0.12 on CRAN! This is a massive update that should resolve many issues with the package (e.g., convergence issues and poor start values).

I am teaching "Research and statistics II" for the first time next semester, which covers ANOVA, correlational/regression analysis and basic psychometrics. I will teach the course using @JASPStats and I am looking for potential textbooks to use for this course. Any suggestions are very welcome!

Ok I'm a million years late to the party, but I finally found my way to bluesky! ✋ Hi! I'm Michèle, a meta-scientist interested in statistical errors & improving overall robustness of psychological science. 🙏 If anyone has tips to build up my network here, please let me know!

3/3 We also look at two families in detail (who had most data) & conduct simulation studies. Thx to all co-authors, incl @sachaepskamp.bsky.social. Paper: www.tandfonline.com/doi/full/10....

📜New article w/Borsboom, @sachaepskamp.bsky.social, Hoekstra, Ostinelli, Bastiaansen & A. Cipriani Towards precision in the diagnostic profiling of patients: leveraging symptom dynamics as a clinical characterisation dimension in the assessment of major depressive disorder🧵 doi.org/10.1192/bjp....

We still have a few open spots for the National University of Singapore professional certification on network psychometrics this summer! See for more info fass.nus.edu.sg/psy/network-....

Incredibly honored to be awarded the @psychscience.bsky.social Janet Taylor Spence award and to see @adelaisvoranu.bsky.social recognized as Rising Star. Given all we faced together, I can't express what an honor it is to be recognized this way at the same time. t.co/5izLnkXk3W t.co/Giy2a99apl

Abstract attached. All are welcome. Date/Time: Tuesday, Jan 23, 9:30am, Singapore (GMT+8). In person: Location: NUS campus, psychology building, room AS4-02-08. Zoom: nus-sg.zoom.us/j/8112130732... Thanks to Sacha Epskamp @sachaepskamp.bsky.social and Utek Leung for organizing.

Part 2 of the Freakonomics series on fraud in academic research is out. With the same people as part 1 (@briannosek.bsky.social @joesimmons.bsky.social @urisohn.bsky.social Leif Nelson, me, and Max Bazerman), plus Ivan Oransky. freakonomics.com/podcast/can-...

APS Fellow @simine.com is introducing new steps to ensure transparency, rigor, and diversity in the pages of Psychological Science.

Ok, Github co-pilot is genually impressive. How does it knows to predict this text here in a slide that I am drafting? The @psychscience.bsky.social STAR editor positions literally exist for only about a week now...

The Psychological Methods group in Amsterdam is looking for an Assistant Professor. Join us! vacatures.uva.nl/UvA/job/Assi...

Another shocking layoff from @posit.co, this time of Yihui Xie yihui.org/en/2024/01/b... Yihui is one of the most influential people in R of all time. His packages fundamentally changed how people work in R & data science more broadly. I'm sponsoring him on GitHub as a token of my gratitude #rstats

Ever wondered how the psychonetrics panel-GVAR (graphical vector auto-regression) models differ from cross-lagged network models and (random intercept) cross-lagged panel models? Then check out this pre-print by Rene Freichel! osf.io/preprints/ps...

Thanks to the work of Ria Hoekstra and the gang, you can now formally compare n=1 idiographic network models with each other, using measurement invariance testing well understood from SEM. Accepted in Psych Methods. osf.io/preprints/ps...

Excited for 2024! Editor: - AE for Behavior Research Methods - AE for Multivariate Behavioral Research - AE for Psychological Methods - STAR (statistics, rigor and transparancy) for Psych Science Workshops: - Invited workshop at M3 conference - Professional certification at NUS Singapore

Thinking of SEM as causal inference is really useful, it becomes a readily apparent that paths in a well fitting model are hypotheses rather than results.

What an incredibly sad day for the Netherlands 😢

Registration for the first ever Asian school on network psychometrics is now open! @adelaisvoranu.bsky.social and me will host two workshops in Singapore from July 29 to August 3. Completing both workshops will also grant professional certification by the NUS. fass.nus.edu.sg/psy/network-...

I have now reviewed several papers that erroneously cite my paper when using a method termed a cross-lagged panel network (CLPN). So to be clear: I did not develop the CLPN and have nothing to do with this method. My paper: link.springer.com/article/10.1... CLPN pre-print: osf.io/preprints/ps...

I recorded a guest lecture on introducing longitudinal network modeling in clinical psychology: www.youtube.com/playlist?lis... The third video especially might be interesting: on cross-sectional/longitudinal data, within/between person effects, ergodicity, and temporal effects.

Very excited about this new preprint in which we solve one of the main issues in network psychometrics: estimating symptom networks in clinically severe populations. This solution is now available in the bootnet, IsingFit, IsingSampler and psychonetrics #Rstats packages! osf.io/xq8ur/

Updating four #Rstats packages on CRAN because of one manuscript... pre-print coming soon!

My department is hiring a tenure track assistant professor in clinical psychology! I am search committee chair! Help us find a new excellent colleague - please share! uofl.wd1.myworkdayjobs.com/en-US/UofLCa...
