🚨 DID Paper Thread 🚨 Are you confused about which new DID estimator to use? A bit more than a year ago, I wrote a short paper that gives a simple answer. I just completed a revision of that paper so here’s a 🧵 to celebrate! 1/N #econtwitter #differenceindifferences

When Double Descent & Benign Overfitting became a thing, I was a masters student in statistics — and so confused. I couldn't reconcile what l had literally just learned about bias-variance&co with modern ML Here's what I wish someone had told me then: arxiv.org/abs/2409.18842 1/n

No defiers is a required assumption for identification of LATE in IV analysis. If that is false, the best thing you can do is to calculate bounds for the LATE. But what happens if limit the maximum proportion of defiers. For instance, what if I don't believe is > 10%?
Niche nerdy tweet incoming: I’m not at all sure about this instrument. The “no defiers” assumption seems unlikely to hold — is there really no possible couple who would have divorced if the husband’s workplace stayed the same but not if it had hired more women?

Fredag aften. Aarhus Cyklebane. Sidste løb på en udendørsbane nogensinde. Køb billet før din nabo. @MichaelMorkov / @Lasse_Norman er det brølstærke par nummer 7. Jørgen Leth kommer til en sidste afsked med en bane, der har en særlig plads i hjertet.

Hey Siri, vis mig et tweet hvor samtlige svar får en Samf-forsker til at græde.
Er det ikke næste for godt til at være sandt, hvad i alverden er det der foregår?

I ran the numbers and they say that 🇩🇰 Vingegaard is on track to beat 🇸🇮 Pogačar at #TDF24 with his week 1 deficit of 1:15. 21-23 TDF averages, Vingo vs. Pogi: Week 1: Vingo loses 1:58 Week 2: Vingo gains 0:58 Week 3: Vingo gains 2:58 cc: @veloropa, @LanterneRougeCP 1/5

As always, this year could just be different (Jonas’ crash, Pogi’s Giro, no Kuss, Remco!, etc.). But it is pretty clear from this data that in a typical year, Jonas’ late tour advantage looks big enough that he should come back and win. 🤷‍♂️ 4/5

Two quick data/methodology notes: I have used the timing of rest days to define what constitutes weeks 1, 2 and 3. I have excluded all time losses on the Champs Elysées stages 5/5

Very happy that today I received a Starting Grant from @DFF_raad. Together with an amazing group (Laust H. Mortensen, @annargrs, @whynotyet), we will explore the potential for using new digital technology to measure learning and better understand learning.
We're proud to announce that @andbjn received a @DFF_raad Sapere Aude grant for his research on intelligent learning tools. 🧑‍🎓 He'll use real-world classroom data to test if these tools actually help students perform better, across social backgrounds. dff.dk/en/apply/supported-re…
