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.
