Raymond Bernard Cattell (1905 - 1998)
Pioneer of Personality Psychology & Intelligence Research
Developed the 16 Personality Factors model and Fluid vs. Crystallized Intelligence theory, revolutionizing the field of psychometrics and personality assessment.

The psychometric assessment
Interested about the psychometric assessment score of Momenul Ahmad:
The accuracy (reliability) of the tests on Momenul Ahmad's Psychometrics assessment Average Alpha is. 88 is considered very good compared to an industry benchmark (>. 70). Validity The test provides good face validity with questions based on modern occupational settings.

I have made updates to the RISEkbmRasch R package vignette for #psychometric analysis, most significantly to the sections on DIF analysis (invariance) and person fit. There are new examples on how to use the `lordif` and `PerFit` packages, amongst other things. https://pgmj.github.io/raschrvignette/RaschRvign.html
My initial instinct was to discount this until I saw the sample size... Interesting. Would like to see the #psychometric measures - and a hint about what my musical choices might say about my #MoralCompass 😂 https://phys.org/news/2023-11-uncovers-link-musical-moral-compass.html
This paper considers the problem of choosing "good" #MachineLearning algorithms from their performance on a number of datasets. They use an idea from #psychometric testing called "item-response theory". A particular benchmark is a single question in a test (some datasets are hard, others are easy). A particular ML algorithm is a student taking a test (some algorithms are consistent, some do well on easy questions, others give puzzling performance).
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

Calling all #psychometric researchers in Norway!
I need a bit of help to figure out how many researchers in Norway are interested in a service that could run behavioural experiments online with data stored in a European legal context provided by the University of Oslo IT.
Please, answer my questionnaire on interest for such a service:

Boosts welcome, I need to reach far beyond my own circle!
I recently (awkwardly) realized that #quartopub code chunks in #rstats do not need labels, which really simplified copy+paste of code you run multiple times in the same document. For me, this is mostly related to re-running #psychometric analysis code when modifying/deleting items.
Also, the :::panel-tabset is great to simplify looking at multiple outputs (and shortening the documentation file).
@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.

Resources needed! There is a lot of marketing out there saying that #psychometric testing removes bias and therefore helps #diversity. This I know is utter tosh because you're literally trying to find people who think the same, therefore are creating a monoculture. I'm trying to fight it being implemented and need resources that show it is detrimental to diversity. Ideally #peerreviewed with examples. #management #recruitment #psychology #resources Boosts most welcome.
