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.

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.

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:

A warning and a plea
- As fields start to use more advanced quantitative / "cause" methods, there is a desire to help consumers of the research (four journal reviewers, editor) to easily assess the study quality and validity (e.g. JAMA causality language)
...
- We need to push against this - need ways to help people understand and assess the (inherently untestable) assumptions in many studies.

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!

@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

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

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?

Screenshot of a guide to identifying errors and misunderstandings in the data. It begins with "When you encounter a new dataset, assume from the start that it contains errors. These errors may stem from how the data was collected, processed, or stored. Additionally, you might misunderstand what the data represents. Such misunderstandings and errors can occur at any stage—from data collection to data delivery to data processing that you’ve done. Before jumping into analysis, your first and most critical task is to "get to know the data." This involves methodically exploring the dataset to uncover potential errors and gaps in understanding."
