No control on the violence now And... what happened to the women and children ???

Imagine a short book (~200 p.) introducing Bayesian statistics in the context of clinical trials and drug development. Scope would be introductory -- sort of "your first short course on Bayes". But practical enough to be applied out of the box. What would you like to see covered in such a text? 👇

We are pleased to announce that Mikael Jagan has joined the R Core Team. #RStats He has been an active contributor to the R project for several years, proposing bug fixes and enhancements. Further, he has been co-authoring/maintaining the important Matrix package and more recently lme4 and glmmTMB.

I have a new favorite editor/IDE: Zed. Open-source, blazing fast, built-in AI operability, easy to use. Heard that lots of developers are dropping Visual Studio Code for Zed. Has R and Quarto extensions. zed.dev

A fantastic reproducibility autopsy that makes me even more dubious of both microbiome & autism research than I was previously & more sickened by how scientific journals work. For them to make money capitalizing on free reviewer labor the least they can do is to be scientific quality gatekeepers.

Donald Trump was posting on Truth Social until 4:10am, including an image of himself as Jesus and multiple posts of the same article, raising alarms about Biden’s cognitive decline.

I've recently made some changes to the gallery of all my data visualisations 📊 Most examples now have links to the underlying source code! If you see something you like, you can see how it was made 🤩 #DataViz #RStats

A huge point about meta-analysis, which begs for reliance on individual patient-level data and adjusting for a full set of covariates.

#Statistics thought of the day: Type I "errors" in frequentist statistics have always been misleading. The "error" exists only inside a stipulated world, not the real one. You cannot call something an error by assuming the very fact that would make it one. #StatsSky fharrell.com/post/journey

Got a personal email out of the blue for a ghost worker. Shameless.

Sending ICE agents to catch undocumented immigrants who attend their child's U.S. Marines graduation ceremony. What does this say about people who think Trump is making America great again?

Wow this is an impressive article from @verawil.de that I highly recommend. One question-how can one get away with "artificially censored at the moment her actual behavior diverges from the assigned strategy" without making some kind of severe independent censoring assumption? #StatsSky #EpiSky

The new V-Dem report was released today. There are dramatic declines in democracy in the US. Much worse than during Trump I.

A journalist filed a brief live blog entry on an apparent Iranian missile strike that hit no one and caused no serious damage. Next thing he knew, angry Polymarket users were demanding he change the story—and threatening his life and family if he refused. My story: wapo.st/4lI6Pon (gift link)

Trump pardons allies who boost his crypto coin. Trump invests in corporations that he's supposed to be regulating. Trump cuts deals with autocrats to advance his family's real estate business. The list goes on. We must not become numb to this blatant corruption.
