Conditional on “the study being published and getting attention” the real effect is likely smaller and not larger. Eg if you assume there is a real effect plus a lot of noise, given the study has been published etc the noise will have more

This is very common in finance. Knowing when finance research that made right predictions with good justifications falls into the "Gettier category" or not is extremely hard.

Yes, but it's potentially more subtle - there's a competition between professional players and casinos, in particular online. There's an interesting bloomberg story on this: https://www.bloomberg.com/news&#x2F

There are many people in group 1 in academia eg in physics and maths that are comfortable with latex and scripting languages but mostly use email to share files. Anything that helps them organise their collaborative work better without hav

In the mathematical sense this is clearly not true - it’s easy to come up with a smooth single mode distribution that doesn’t look like a bell.

Published in an MDPI journal so the prior should be that it’s not serious research, unfortunately.

No, eg (Corr(A, B) = 0) and (Corr(A, B) > 0 | f(A)) can say something nontrivial about f.

While this might well be correct, the argument is missing that academic qualifications conditional on growing up in the US (as supposed to in Afghanistan) are still a proxy for potentially useful skills. In other words, some of the enemie

How about 220 Hz music and 880 Hz? (Obviously this study won’t replicate and categorising music by the frequency of the note A is not a reasonable thing to do.)

Yes, it's easier for mathematicians, because a lot of background knowledge and intuition is encoded in mathematical conventions (eg "C(R)" for continuous functions on the reals etc...). Note that this is probably a book for m

Unfortunately the stock market is not (reflective of) the economy? It seems reasonable to force them to diversify nonetheless.

The two graphs have visibly quite different volatilities. A number like 20% is not meaningful unless you also somehow state the risk, eg in terms of volatility or beta or other measures.

Yeah, of course, if the name is clearly absurd you’d use the insights from that and update your posterior, and if you have more information about the person you can include it in the prior. The point was that 1/n over all possible name

This is a nice insight. I slightly disagree with the first example in a gambling context, although it makes sense in the context of information theory. I don’t think the choice of prior is right when giving 20:1 posterior odds you’d be wi

Thanks, this is a nice reference! Interesting that the abstract and introduction mention the lack of existing evidence - seems like an under-studied question? One aspect that's quite easy to criticise about this study is that it uses e

They probably found many small things and combined them extremely well. In quant trading, if you've got a lot of excellent researchers, chances are that you make better choices in lots of "micro" decisions that add up to a su

Yes, like, all uniquely shaped ones?

by conformist 3y ago
I think this is a relatively weak argument, because in colloquial English “the shape” sort of implies uniqueness in the question?

Ah, yes, and they do indeed cite Barnes-Hut, too. So the (claimed) novelty seems to be how they connect it to Monte Carlo steps.

Arxiv: https://arxiv.org/abs/2207.14670 If I understand correctly after skimming, one of the fundamental ideas behind this appears to be similar to the well-known Fast Multiple Method [1]. It’s also a tree-based approa

This is clearly meant to be humorous etc, but just to explain a part of what’s happening here: Regressing price levels (integrated series) against each other does not lead to meaningful R^2 values and is considered a “chart crime”. See [1
