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!

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.
