Inspired by @emilyriederer.bsky.social, I made some pictures for my seminar on causal inference. They are not labeled. Let's see if you can name that research design.

This paper taught me that the competition between advertisers for the most desirable ad slots is really important.

Chat GPT just gave me the best complement on my writing I've ever gotten.

How frequently do you meet with your students? Once a week just doesn't feel like enough when you are in the "thick" of a project.

What a week, huh?

In reviewing dplyr code written by a PhD student, I'm reminded of how useful base R functions like summary() and str() are for inspecting data and detecting errors.

Happy to report that this paper has been accepted at Management Science! (At least that was reported in the ISMS Newsletter, but I can't find the paper on the Management Science website.

Joo and Chiong’s recent working paper provides a Gaussian approximation to the regret function that you can use with ✨any✨ asymptotically normal estimator. This means you can use the minimax-regret criteria with your favorite treatment effect estimators: diff-in-diff, ML estimators.

An important plea from @lizstuart.bsky.social in today's SCI-OCIS Special Webinar Series:

#Eagles and #Dragons fly together! 💚🦅🤍 💙🐉💛 Drexel will close on Friday to join the rest of #Philly in celebrating the Champions!

@septaphilly.bsky.social which is it?

We are seeing some impact on reproducibility efforts with the transition to the new US administration. For now, I suggest that you make backups of any data that required you to actively interact with the Federal government, as there may be a delay in response times.... #openscience

Toying with the idea of using RStudio + #quarto + github to manage content for my doctoral seminar on causal inference. I'd like to be able to create short "explainer" documents that integrate math + code + hyperlinks. I don't want this to be a major project. Thoughts on design and workflow?

Regardless of where you stand politically, the separation of powers is a fundamental principle of American democracy. The President should pursue policy goals by working with Congress—not through unilateral actions that undermine the constitutional process and sow uncertainty.

Hey Science Queen @ekoenig8.bsky.social: I've noticed the snow melting this week, even though it has been well below freezing. How does this happen? Is the snow sublimating? Or does it melt than freeze? TIA!

Lots of folks are discovering the relevance of decision theory to the practical problem of analyzing an A/B. A quick🧵

New favorite term: plasmode simulation

I'm gearing up to teach @callingbullshit.bsky.social at Drexel during Winter term. I had forgotten how much I love this material. Thanks to @carlbergstrom.com and @jevinwest.bsky.social for putting it together.

Writing base R makes me feel the way your great aunt Janine feels when the wedding DJ plays a favorite song from her youth.

@quantuxblog.com convinced me that you can explain mathematical concepts with code just was well as with athematical notation when we wrote R for Marketing. It was nice to see that @allendowney.bsky.social feels the same way in his latest email. #rejectmathsupremacy #probablyoverthinkingit

For everyone: How many times have you had to use a fire extinguisher?

This is just so #Drexel. A fashion design student raises money for student activities by setting up a curated thrift shop with clothes donated at moveout. drexel.edu/news/archive...

Does anyone have experience with py-feat? #python #facialrecognition #emotionrecognition #marketingacad

Anyone have strong opinions about facial expression / emotion tracking software? What would be best for a lab just getting started with this?

Grading MKTG367 digital campaigns, I'm noticing that a growing gap between what users see on the Meta Ads interface and what is happening "under-the-hood" in the ad auction. Not one of the teams capped their bid. Is this an "Advantage +" for advertisers or for Meta? #digitalmarketing #marketingacad

This thermos really is *perfect*.

@johnclithero.bsky.social, @umakarma.bsky.social is there a starter pack for neuromarketing and/or physiological methods in marketing?

I'm writing a guide to identifying errors and misunderstandings in marketing data for my doctoral students. What other resources should I be aware of?

Effects coding should be your default.

This is one of my favorite #Drexel Veteran’s Day traditions. #DrexelWelcomeAll #DrexelWelcomesVeterans

I can hear the bagpipes playing in honor of Veteran's Day from my 8th floor office.

I’m excited to get back in the habit of posting random thoughts when I’m bored with whatever I’m supposed to be writing.

Has anyone made a starter pack for marketing academics? It's looking kinda prescient that we chose #MarketingAcad and not #MarketingTwitter.
