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!

Observed correlations between person-means depend on within-person correlations This paper highlights how within-person correlations affect between-person correlations, with implications for statistical interpretation.

YouTube video by Psych #rstats Club Introduction to CFA & Structural Equation Modelling in R

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...

Yes! I am using this as one of the two textbooks in my course now!

Two more weeks to register for our workshops on network psychometrics and longitudinal data modeling in Singapore next month! Registration closes July 15.

Psychometric network modeling with psychonetrics Workshop materials for the Modern Modeling Methods (M3) 2024 pre-conference workshop Hosted on the Open Science Framework

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.

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-....

I got that too! Given that they didn’t even know my affiliation I guessed it was spam.

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.
