"That’s why the Center for Scientific Integrity, the nonprofit organization behind Retraction Watch, has launched a new annual award celebrating scientists who discover substantial errors in their published work and take meaningful steps to correct the scientific record."

What RFK Jr.’s CDC Doesn’t Want You to Know
open.substack.com/pub/pauloffi...
RFK Jr.'s CDC is hiding information about outbreaks of vaccine-preventable diseases.
"A study... showed that last season’s 2024–2025 mRNA COVID vaccines reduced people’s risk of emergency department visits by 29 percent, their risk of hospitalizations by 39 percent and their risk of death by 64 percent. ”"

I guess that’s the kind of governing body that thinks this is a good idea.
It’s rare, but not unheard of, for non-monarchs to put their faces on coins.

Forskerforum has written a piece about my unfortunate experience with the Danish Office for Naturalization (in Danish)

More volatility and uncertainty from the White House. An abrupt rule change for H1B visa holders. This is not in 🇺🇸 interest.

Offsets between Harasheh et al. (2023,Table 1) and Ha (2023, Table 1)
A surprising result. Let
X = Harasheh et al. (2023,Table 1)
Y = Ha (2023, Table 1)
Z = Table in image
Then X - Y = Z.

Who said ❄️❄️❄️
These are just two of many articles in #Economics journals that I have found similar issues with -- some are in journals with Impact Factors >10.
I plan to comment on additional papers, but there more than I will have time to address. #EconSky #OpenScience @pubpeer.com @datacolada.bsky.social
Instead of replying on PubPeer, the lead author of the other paper emailed me directly, which didn’t address why the figures are virtually indistinguishable.
I encourage them to post a short reproducibility package and link it on PubPeer, so readers can verify.

Coşkun et al. (2023) looks legit: based on a PhD dissertation; data/code on GitHub; public post on LinkedIn.
Yet this specific figure doesn’t match their data on Github. Also, signs suggest the upper panel is returns (±), and lower panel is volume (>0).🤔

I recently wrote my first comments on @pubpeer.com
Two papers—different assets & sample periods—appear to use the same figure.
How did one plot end up representing different variables?

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'

Moments by Integrating the Moment Generating Function co-authored with Chen Tong (Xiamen).
I believe this result is useful in many fields. Anyone know the proper outlet for this type of result? #arXiv #OpenScience
arxiv.org/abs/2410.23587
The CMGF method provides a simple integral formula that yields fractional, absolute, central, and even complex moments — without relying on the density function or any derivatives.
For example,
E|X|^0.7 or tail moments
E[(X - ξ)^3 1{X > ξ}].
It is fast: NIG example:
he new method avoids derivatives entirely, is fast, general, and easy to implement.
We call it CMGF, because it uses a complex argument for the MGF (also nests the characteristic function).
And it applies to complex moments too. #Physics
Unfortunately, for fractional moments — or in dynamic models where MGFs are defined recursively — computing derivatives can be difficult, slow, or even infeasible. Existing methods often involve fractional derivatives or integrals with messy expressions.
It's well known that the k-th integer moment is given by the k-th derivative of the MGF evaluated at zero. This is simple, clean, and taught in many probability courses.
But it has limitations. It only works if you want an integer moment, and can take the derivatives you need.
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

I suspect that the leadership at Columbia includes one person with faculty experience or at least a PhD. We are not so lucky.
