Brandolini's Law on Bullshit Asymmetry
»The amount of energy necessary to refute bullshit is an order of magnitude bigger than to produce it«
―Alberto Brandolini
Will also be proven to be correct in regard to #COVID19 nonsense.

For modeling economic data with cluster structures and complex dependencies.

Ugh. Why is @SpringerNature still publishing crap like this? I am not referring to the low quality of the panels. Can you spot the actual problem?

Some economists treat it as gospel, as evident from @GarettJones’s sermons… I mean, lectures. :-)

I added comments on additional papers on PubPeer and wrote up a LinkedIn article.

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

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

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 reproducibility package and link it on PubPeer, so readers can verify.

Indeed. Many very promising mRNA 💉 cancer treatments in the pipeline.

Man har en dårlig sag når man ikke kan skelne lobbyisme fra uafhængige råd der argumenterer med saglig analyse og faglig ekspertise fra øverste hylde. Eva Kjer Hansen (V) vil nedlægge Økonomisk,Etisk,Klimaråd. Hvorfor stoppe der? Hvad med: Traffik-,Miljø-,Natur-.Sundhedsstyrelse?

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
English
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:

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

Dr. Hiviid responds to the claims of RFK Jr’s Dept HHS. Dr. Hiviid, please know that many (if not most) of us in U.S. biomedical community do not support the junk science of a corrupt wellness/influencer industry & its pseudoscience agenda, we’re with you trialsitenews.com/a/data-vs.-dou…
