In statistics and also in politics, if more people realised the 'the past is not on offer' analysis and decision-making would improve considerably.

here's another paper recommended by
@hagmnn that tackles the problem more directly but is much tougher to read, approach with enthusiasm for mathematics:https://link.springer.com/article/10.1007/s10958-006-0366-5 …Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
It's been pointed out by
@hagmnn that the wiki misleadingly makes it seem that the problem has been satisfyingly solved -- when it has not!!

It is possible--again, stay with me here--that when candidates tweet predictions about election results, their goal isn't to minimize mean squared error.

"robust" (Eiker-Huber-White) style standard errors are substantially biased downwards in many cases - especially those with a few "high leverage" data points, which Young 2019 finds in much of applied work. See Chesher and Jewitt 1987 for the proof: https://www.jstor.org/stable/pdf/1911269.pdf …

I think I hurt my hip while I was working out. I just stood up from the desk, felt the pain in my hip, and said the following things out loud to nobody in my office: "Owwww, far out, christ, fuck,....I need biscuits."

the most interesting, confusing and beautiful things about statistics lie at its foundations and show themselves in its simplest operations. nothing can be taken for granted, one is plunged again and again into uncertainty. it's so exciting!

Every now and then I forget and re-remember that the classical t-test of differences in means across groups assumes the variance of the two groups is the same, which is almost certainly problematic. The Behrens-Fisher problem! One of my faves: https://en.wikipedia.org/wiki/Behrens%E2%80%93Fisher_problem …

The politeness rule--that if you can't say something positive, don't say anything at all--is close to reversed in intellectual contexts: if you don't have an objection, stay silent. So 'mixed' contexts (e.g. Twitter) create problems.

See, people think Anscombe's quartet is all artificial extreme cases and no one would actually make such a stupid mistake with regression, and then you get figures like Fig 8C https://www.jneurosci.org/content/32/11/3791.full …pic.twitter.com/sEG3BXpQYj

One of the nice things about Andrew Gelman's blog is how benign posts routinely produce deep debates about foundations of statistics. This time, the concept of "calibration" (see comments): https://statmodeling.stat.columbia.edu/2020/02/01/forget-about-multiple-testing-corrections-actually-forget-about-hypothesis-testing-entirely/ … My attitude (new box in 2nd ed of my book):pic.twitter.com/TiP4n0TapN

I remember some advice
@ben_golub gave me to try to not be singularly focused on writing a job market paper, which encouraged me to revisit an old idea. That idea led to a better idea that eventually became my job market paper.https://twitter.com/ben_golub/status/1223193782658764800 …Hvala.
