Me riding a skateboard in a park. I have on a blue dress with white polka dots, leggings and off-brand skate shoes. My arms are out because I'm still learning to balance.
Me on a skateboard, with hair in my face despite the hair tie.

In think this depends on a lot of implementation details; if the second ridge is a small area in a big space, DE will take a while to find it, while PT will get there faster due to the flat parts. But honestly, Pigeons has some additional tricks that help, and is easy to just plug in to try.
Any thoughts on Differential Evolution vs other samplers that tend to work well for multimodal cases? I have had good luck with parallel tempering, which has a nice software implementation that can take in a Stan program. github.com/julia-temper...
No Moore-Penrose pseudoinverse? That's fine for theorems about beta, less so for predicted values and residuals. Invertibility is fine as a sufficient but not necessary condition.
Clearly this is a story about compensating differentials; meeting blue haired people is a valuable amenity and rational workers will accept it as part of the total value of the labor contract. That's surely what they meant, right? 🙃
Oh, they/he. My sources were incomplete.
Also, important fact from Google translating the coming out announcement, I learned it's pronounced "AFAB toransumasukyurin nonbainarī" in Japanese.
Aren't they non-binary? We need more poetic innovation in stock phrases for attractive non-binary people which can match proper scansion and fit in a rhyme scheme. Along with perhaps more radically inclusive changes in the thematic content of pop music.
Yes, XG counts too! They changed all the "girls" lyrics after Cocona came out.
I was thinking the Underscores remix with Loona's Yves, who's been on a "you can't even call it queerbaiting at this point" kick lately.
Oh, from Nmixx, I've just started getting into them!
Their song with Pabllo Vittar where they sing in Portuguese on a pride float during Carnival is probably my second favorite recent K-pop colab with a trans artist.
If it makes you feel any better, I didn't know until you mentioned it that Tame Impala is Australian. We all have our blind spots.
Jennie is a Kiwi and got her start collaborating with Australians! Blackpink's Rosé is from Melbourne.
You would know this if you read theory (watched the Blackpink documentary on Netflix).
The context Lévy–Itô decomposition theorem says that any context is the sum of context drift, context jump, and context diffusion.
This is the most notable argument in "The Incoherence of the Philosophers" by al Ghazali. An all-timer title, and arguably still a defensible stance on causal inference.
This thread only scratches the surface of his output including quite a bit of work w/ contemporary policy impact. Our UZH Fiscal Policy reading group has been slowly going through several of the papers this semester to catch up. W/ the method in Dynare the use will likely continue to accelerate.
On policy, the approach has allowed simpler characterizations of (Ramsey) optimal tax policy w/ het agents, previously a computationally hard task prone to errors straub.scholars.harvard.edu/file_url/156 echoing his earlier work fixing longstanding errors in the literature on capital taxation.
This empirical tractability has helped econometricians tie equilibrium models more directly to the output of "causal" time series models and clarified what kinds of shocks are needed to identify policy effects: see papers by Wolf et al, eg dx.doi.org/10.1257/aer.... and below:
The key object, an ∞-dim Jacobian of equilibrium outcomes at time i wrt shocks at time j, allows for extending Keynesian cross intuition based on MPCs to intertemporal models w/ heterogeneity, defined in terms of IRFs wrt a sequence of news shocks amenable to estimation w/ Local Projections
Not long afterwards, I noted that it began being applied in all kinds of macro applications relating inequality to monetary & fiscal policy & business cycles, most notably by Ludwig himself, pushing HANK (Heterogeneous Agent New Keynesian) towards normal science and a consensus macro model.
For a summary, the week the WP came out I excitedly wrote an explanatory thread on Sequence Space Jacobians emphasizing links and contrasts to existing Heterogenous Agent methods and the Wold representation in time series. That excitement has subsequently been matched by the takeup by the profession
Well-deserved recognition for @ludwigstraub.bsky.social! His work w/ coauthors on "sequence-space" methods has transformed computation, empirics, and policy analysis in macro, offering a model representation which is general, intuitive, computationally tractable, and amenable to empirical testing.
Apologies, I had meant to link to an interview with Sweeney, not the story about her, which is less focused on management issues

Some interesting descriptions of management practices here clarify the "who" and "what" and maybe provide some partial insight into "why."

Cover of "The Identity Matrix" by Jack L. Chalker The cover art is a drawing of a woman below a UFO-style spacecraft.
Back Cover of "The Identity Matrix" Text: The Invaders are among us "While backpacking in Alaska, Victor Ganser, a 35-year-old Ph.D. in political science, finds himself trapped in the body of a 13-year-old Tlingit Indian girl. A little later he is forced from there into the spectacularly beautiful body of an 18-year-old blonde. He finds that the switches are part of a skirmish for Earth by two alien races... And that's just the beginning. Like many of Jack Chalker's earlier books, this one is almost totally unpredictable and will keep you guessing to the last page."
I found a copy in a used book store several years ago and picked it up solely to make a Linear Algebra joke about the title.
Anyway, I'm a woman now.
As for reasonable noise levels, it's worth noting, as a 🏳️⚧️ person on X, I block about 50-100 new accounts/day explicitly calling for my death, allocating <2 seconds each, likely including a fair number of false +s. A sensitive classifier in that environment necessarily lacks interpretive charity.
As for why beliefs might be such that a post gets put in that bucket, you don't need systematic bias, only noisy evaluation, which is inevitable in pooling equilibrium in which outgroup and ingroup distributions overlap. There will always be some "incorrect" beliefs even with an optimal classifier.
I think a much more plausible story is just correlation neglect, ie, given that some post falls into the "complain about it" bucket, one only partly internalizes that others may also do the same, resulting in a "pile" of complaints that may be more severe than the intended severity of each one.
Right, in HANK models income risk is significant for dynamics via implications for cyclicality of precautionary savings. In baseline HANK models, that risk is purely exogenous so passthrough has to be calibrated directly from shocks, but the underlying mechanism clearly goes through labor markets.
Nice! From the abstract it looks like heterogeneity is a key part of the mechanism, which I suspected was important for the macroeconomic implications.
In a model with heterogeneity, monopsony should have consequences for the distribution of cyclical income risk, and with search for unemployment and match efficiency, so it certainly can do more. I'm just a bit puzzled as to why standard NK models chose to put the market power the "wrong way".
Why not in a basic model: if you impose market power on the producer side via a monopsonistically competitive job aggregator, you get markdowns instead of markups, but w/ Calvo wage-setting frictions you should get the same wage Phillips curve up to the constant term after linearization.
