@SEPTA_SOCIAL Yes. I was at Wawa. No announcements until 7:50ish.
@SEPTA_SOCIAL where is the 7:25 inbound train from Wawa? No train. No announcement. No alert in the app. There are about 100 of us just standing on the platform wondering what to do.
@SEPTA_SOCIAL Thanks! There weren’t any announcements until it was over 20 minutes late.
Check out some of the cool events on global trade and sanctions that my colleagues at the new @DrexelCGPA are planning!
@brett__gordon and @CaioWaisman expertly show advertisers how to design their experiments to estimate the thing they need to know to make the decisions they want to make.
Paper with @CaioWaisman finally out in articles in advance. WP version: arxiv.org/abs/2302.13857
Goodbye X. You can find me over at BS. Still @eleafeit over there.
🎇 PhD student internships in Computational Social Science at Microsoft Research NYC 🎇 These are 12 week, in person internships with some combo of Dan Goldstein, Jake Hofman, & David Rothschild Early (January - April) start dates somewhat preferred jobs.careers.microsoft.com/global/en/job/…
You want to know the effect of some treatment on an outcome and have a time series of outcomes for each subject pre- and post-treatment. Access to treatment is regional and is arguably quasi-random. Compliance is definitely not random. What analysis would you do?
On September 13, 1826, Anthony J. Drexel was born in Philadelphia. Happy birthday to our university's founder!
To set advertising budgets, you really need to know the _marginal_ incremetality. This paper shows how to design an experiment to measure marginal incrementality. Super important!
Treatment/control incrementally experiments measure the total incrementally of a campaign. That's great if you are trying to decide whether or not to use a particular channel, but...
How many consumers should a campaign reach or what budget should be set? @CaioWaisman and I present a method for these *intensive margin* ad decisions. 📜"Multi-cell experiments for marginal treatment effect estimation of digital ads", soon at MngSci. arxiv.org/abs/2302.13857

@brett__gordon @CaioWaisman Congrats to @brett__gordon and @CaioWaisman
@DanielPosen @JohnHelveston I’ve been organizing conferences for a few years and can confirm that hotel and convention center costs are going up. Universities can be cheaper but it can be hard for them to handle more that a few hundred.
I'm very sad to share the news that my dear colleague @DanielKorschun passed away last week. He brought an endless supply of espresso and optimism to our department that I will miss. You can read more at mailchi.mp/lebow/remember…
@d_mccar @ama_journals I meant it! I’ve only read one of your reviews (afaik) and it was spot on.
@d_mccar @ama_journals Well deserved! You’re going to be great!
How is it that I can stream TikTok's all day long, but getting a weather radar animation takes for-ev-er?
