One takeaway from the paper is that disclosure is necessary but not sufficient: Franchise Disclosure Documents make these restraints visible, but they do not undo switching costs,hold-up, or post-term noncompetes.

The FTC's Franchise Rule emphasizes disclosure over substantive regulation.

I see it now. elegant!

Very nice design with the “+” operator. I did my homebrew with function arguments. Does prefab allow you to customize? eg via templates?

Identification Strategies This chart shows the frequency of papers matching the following search query: "causal identification" OR "causally identified" OR "identification strategy" OR "identification approach" OR "identification assumption" OR "identifying assumption" OR "identifying variation" OR "empirical identification" OR "over identified" OR "over-identified" OR "underidentified" OR "under-identified" OR "identification properties" OR "identification test" OR "identification problem" OR "identification issue" OR "problem with identification" OR "problems with identification" OR "issue with identification" OR "issues with identification" OR "problem identifying" OR "problems identifying" OR "issue identifying" OR "issues identifying" OR "threat to identification" OR "threats to identification" OR "threat for identification" OR "threats for identification" OR "over identifying" OR "over-identifying" OR "under identifying" OR "underidentifying" OR "partial identification" OR "partially identified" OR "non-parametric identification" OR "nonparametric identification" OR "non parametric identification" OR "non-parametrically identified" OR "nonparametrically identified" OR "non parametrically identified" OR "identification condition" OR "identifying condition" OR "condition for identification" OR "conditions for identification" OR "condition for identifying" OR "conditions for identifying" OR "point identification" OR "pointidentification" OR "point identified" OR "point-identified" OR "point identifying" OR "point-identifying" OR "set identification" OR "set-identification" OR "set identified" OR "setidentified" OR "set identifying" OR "set-identifying" OR "identification analysis" OR "weak identification" OR "identification result" OR "identification argument" OR "identification framework" OR "identification scheme"

@paulgp.com where do the 70-90% identification rates from the dashboard website come from? I can't find them in the paper (or I'm reading it wrong).

I take this as a serious question: if everyone (every LLM) uses the same seed it sort of defies its purpose and it’s well documented that these models tend yield the most probable input which for seed is 42 (because programmers love the Hitchhiker's Guide to the Galaxy?!)

`tidy-r` SKILL.md got a spring clean! I slimmed down the reference, added `tidyselect` coverage, and fixed a few things. It's one line to install.

Amazing work! Are you planning to support `tar_file` and the rest of the zoo?

A screenshot of the positron app showing it was modified on January 1, 1980.

This made me chuckle @posit.co #positron #rstats

So they positron dev containers are not intended as a claude code yolo sandbox? or also? 😅

Congrats, looks great. I would love to test it: I have a simple project that replicates code in three languages (R, Python, Stata), one that builds a method based on a replication package (R), and a more complicated model that dispatches to Stan.

Do you think one of them would be a good candidate?

Is this not a tool for sandboxing? I guess I’m unclear about the use cases.

Is this for the infamous ‘—dangerously-skip-permissions’?

Maybe I'm doing it wrong: does the search find the replicated papers? E.g. osf.io/registries/s... returns zeros results but the paper in here does mention that author as part of the paper: osf.io/rq6jd/overview

This is helpful! Is there also a direct link to the list of all attempted replicated papers?

Send me your favorite #rstats hex tile.

It includes all the cool new functions of dplyr 1.2! It also hooks into the r-btw MCP server for live docs, or falls back to R help when it's not available.

Some juicy prizes for an essay.

Thanks for sharing. Just FYI, I recommend to audit the event-studies skill manually because it has set.seed(42), broken file paths, and every plot example (I think?) uses geom_ribbon when the instructions explicitly said geom_errorbar.
