#psychometric — Public Fediverse posts

purrr -> furrr is such a wonderful thing for parallel processing in #rstats. I’m running #Rasch #psychometric models for 52500 simulated datasets, comparing packages/estimators, and the speed-up is very nice when going from single core to 8 parallel cores. And so simple to implement!

I've finally managed to put together a sort of vignette for the #rstats package for conducting #Rasch #psychometric analysis documented with #quartopub : https://pgmj.github.io/raschrvignette/RaschRvign.html

@lakens I’m wrapping up a paper where we propose new reporting guidelines for #psychometric papers that clarify basic criteria for measurement. I’ve developed an #Rstats package that vastly simplifies conducting #Rasch analysis with #quartopub that follows our reporting guidelines. We also include a brief checklist for intervention scientists to assess psychometric quality of measures. Hopefully this is useful to improve quality of measurement. Preprint available in December.
