It’s almost too good to be true… but you can map an empirical correlation matrix into approximately uncorrelated and standardized variables. The generalized Fisher transform makes this possible. Link to latest draft of working paper with Ilya Archakov. #GFT #Econometrics

What RFK Jr.’s CDC Doesn’t Want You to Know
The CDC is withholding critical information about vaccine-preventable diseases from the American public. Why?

For international til at blive dansker
AU-professor Eric Hillebrand troede, at det efter 13 år i Danmark som fastansat forsker ville være en formssag at få statsborgerskab. Men nej – han rejser for meget.

More volatility and uncertainty from the White House. An abrupt rule change for H1B visa holders. This is not in 🇺🇸 interest.
Gergely Orosz@gergely.pragmaticengineer.com · 12mo agoThose on an H1B cannot return to the US from tomorrow (Sunday) unless paying $100K. This is an out-of-the blue presidential action. We’ll see software engineers stranded abroad. One easy to predict outcome: those on US visas will travel less… for work, for conferences etc.
A surprising result. Let X = Harasheh et al. (2023,Table 1) Y = Ha (2023, Table 1) Z = Table in image Then X - Y = Z.

🏆 Research integrity consultant and image forensics expert @elisabethbik.bsky.social has uncovered fraudulent data in over 7,600 scientific papers and exposed the practices of ‘paper mills’ that produce counterfeit scientific articles. She is honoured with the €200K Individual Award. Congrats!
Hi @pubpeer.com Have written many comments and have many yet to address. I believe I follow guidelines, but some posts end up as: "comment moderated by admin (For further information, please consult our commenting guidelines)". But I cannot figure out why. Can anyone help? Below is an example.
After the break, we will continue with the next session: "Authorship and Integrity Issues", introduced and moderated by Lex Bouter @lexbouter.bsky.social The first speaker (program change) is Tim Kersjes with 'Paper Mill Use of Fake Personas to Manipulate the Peer Review Process' #PRC10
Give the man a break. At 73, a few minutes of blissful peak performance is impressive. #UNC If you don’t know better — it’s $10M well spent.
We have discovered a new way to compute moments of a random variable with a moment-generating function (MGF). All sorts of moments. #Statistics #Probability #Econometrics
Faculty experience—or even a PhD—is not essential for every university leader, despite research and education being what we do. However, when no one in university leadership has it, this can be the outcome 👇 @UNC www.theassemblync.com/education/hi...

Vingegaard præstation i dag var “the best long climbing performance ever” på trods af Pogacar var 2 sek. hurtigere. 6.52 ᵉW/Kg for 54:32 min. lanternerouge.com/2025/07/22/h...

Ser kommentarer som ser dette som tegn på doping, og jeg undrede mig også sidste år, hvor Vingegaard og Pogacar begge havde præstationer på Armstrong/Riss niveau. Men der har været forbedringer af grej og hypoxic training som delvist (og lovligt) giver samme effect som EPO. #LivingHighTrainingLow

Pogačar's tid var imponerende. Ifølge CyclingGraphs var præstationen 6.74 ᵉW/Kg for 35:11 min 🔴 på grafen for Pogačar præstationer frem til TdF 2022, hvor Vingegaard vandt på Hautacam 🟣 6.32 ᵉW/Kg for 36:37 min
Trumps handelskrig er et stort opgør med en den regelbaserede frihandel, der er et vigtigt fundament for en moderne markedsøkonomi som den amerikanske. På tilsvarende vis er uafhængige centralbanker en vigtig del af fundamentet. En utrolig vigtig del, faktisk
