I was doing Applied Math in my undergrads and my PhD, working on computational fluid dynamics. Recent events on the Navier-Stokes equations are certainly both exciting and controversial. Here are two brilliant and quite accessible videos on the topic: First one, Quanta Magazine always delivers:

I guess in a non-hierarchical model you want an overall "intercept" that corresponds to the actual average of the level-specific intercepts.

How would you combine the sum to zero (hard constraint) with the normal(0,sigma) (soft constraint)?

Last year, I publicly complained multiple times (see e.g. elevanth.org/blog/2025/07...) that the open access movement had been captured by publishers, and we are now worse off than before open access. Well people got mad at me for saying it. But I think things are still getting worse.

Agreed. I'm trying my best advertising that one can do actual nonlinear statistical modeling & testing in brms quite conveniently, instead of just fitting a curve through some data

Unsere Kritik hat immerhin den Nonsens der Bestrafung schnellerer Promotionen abgeräumt. Aber es bleibt dabei: Die Pläne für die Novelle des #WissZeitVG sind lächerlich. Postdoc-Phase bleibt prekär wie gehabt. Anti-Werbung für Wissenschaft als Beruf in D. Da muss sich noch viel ändern! #IchBinHanna
Vor allem aus der Postdoc- und Mittelbauszene kam scharfer Protest. Die Initiative "#IchbinHanna" warnte vor einem Fehlanreiz, die Promotionsphase möglichst weit auszureizen, und vor einer Verschlechterung für schnell Promovierte. Jetzt gelten die insgesamt zwölf Jahre weiter wie bisher: Wer beispielsweise nach vier Jahren promoviert, kann die übrigen zwei Jahre weiterhin zusätzlich in der Postdoc-Phase nutzen.
Schnelle Promotionen verkürzen damit nicht automatisch die anschließende Qualifizierungszeit.

The workshop title is bait. I will convince you that it's easy to move away from simple curve fitting, and perform proper statistical analyses: include treatment variables & random effects, perform model checking & hypothesis testing. (2/2)

🌍 How does biodiversity keep ecosystems functioning? A new study, published today in Nature, shows that healthy ecosystems depend on more than simply having many species. What really matters is the complex web of interactions between plants, herbivores and predators.
