Mit diesen vier Methoden schüchtert die AfD Lehrkräfte ein

Wir haben in den vergangenen Monaten unzählige vermeintliche Einzelfälle analysiert. Nun ist klar: Der Angriff der Rechtsextremen auf das Schulsystem folgt einem klaren Muster.

Konservative 🤝Rechtsextreme = politischer Selbstmord?

In vielen EU-Ländern versuchen konservative Parteien durch Kooperationen, rechtsextreme Parteien zu „zähmen“. Die CDU-nahe Konrad-Adenauer-Stiftung hat untersucht, was das für Konsequenzen hat. Spoiler: Es funktioniert nicht. 1/6🧵

That's interesting - thanks for comparing the methods and for letting me know!

Analytical solutions are of course more elegant than numerical integration.

Just a remark regarding "The same incorrect computation appears in implementations of latent-trait multinomial processing tree models":

The issue has been mentioned in the literature (shorturl.at/Ajx0W), and the R package TreeBUGS has the function probitInverse as a solution (shorturl.at/mRp1S).

Looks and reads great, I especially like the concise figure!

This is an important issue which is often overlooked, so the contribution will be useful for many modelers. 👍

1/3 I think the premise is worth some attention: why is there a (frequently wrong) expectation that science is precise? I am often confused even by textbooks for university student audiences. Confused about how frequently findings and expert judgements are portrayed as certain and final.

It would be good to learn already in school that uncertainty is a fundamental aspect of science.

I guess people generally dislike being in a cognitive state of uncertainty. But I vaguely remember some studies showing that scientists are better at coping with it.

Just submitted a minor bugfix of RRreg to CRAN:
github.com/danheck/RRre...

The R package focuses on analyzing univariate & multivariate data collected with the Randomized Response Technique (RRT), which protects anonymity in surveys by randomly scrambling responses.

I also added a new logo 🚀

I’m sick of the mainstream media using euphemisms and other weasel wording to soft-pedal the Trump regime’s corruption.
Rather than committing crimes, Trump “sidesteps laws.”
Rather than lying, he’s “untethered to truth” or “inverting the facts.”
Read my latest Stop the Presses newsletter.
