Moral of the story: IV designs have much larger uncertainty + publication bias/file drawer --> Much bigger IV estimates than OLS (with potentially much greater biases).

This is such a beatiful paper, many congrats to the authors!

Thank you, Chenggang. Appreciate your invaluable contribution. I wish I could get back to my little podcast business... Too much fun with research recently.

Is it just me, or is Google Drive insanely harder to use & to organize as a cloud storage service (vs. Dropbox)?

We lost a true pioneer today. Rest in Peace Danny. While our work did not always agree, I always felt that I received a fair trial with you. We will all miss your brilliance, vision, and wisdom.

1988年许老师、钱老师、裴老师等五位留学生访台😁 youtu.be/dyTQiRmN4ew

刚刚被普京当局宣布在服刑狱中去世的俄罗斯反对派领袖纳瓦尔尼，在加拿大导演Daniel Roher 2022年纪录片《纳瓦尔尼》里，被问，“如果有一天，你被捕入狱或者不幸被害，你想给俄罗斯人留下什么样的信息？”对着镜头，纳瓦尔尼目光坚定用俄语说 “不要放弃”。 #Navalny

My heart sank as I read the news about #Navalny . I remember meeting him at an event in London much before he became the main opposition leader. He was humble, thoughtful, and laser-focused on his mission. The cruelty of #Putin 's regime is hard to characterize in words.

Yay. Way to go, Thomas!

Welcome back, Kaiser!

Now that every website has a talk-to-AI button, I've begun to develop a social phobia towards AI. Is this normal?

I'm seeking a predoctoral fellow to develop tools for causal inference using panel data. Application deadline: Feb 29. iriss.stanford.edu/predoctoral-sc… (Project E).
The staff position requires US citizenship, a green card, or OPT.

Congrats, Simon!

Whoever tells you “we understand deep learning” just show them this. Fractals of the loss landscape as a function of hyperparameters even for small two layers nets. Incredible

This is Chenggang's authentic X account.

Way to go! Great paper by Fangqi, Erik, and Michael.
