State of Open Data talk
Brian Nosek brings up something I've been thinking about.
Pre-AI - Benefits of data sharing often exceeded the costs (most people use your data for good)
Post-AI - People have real concerns about how their open data will be used for things they don't ethically agree with

While the data files are fairly self explanatory, I don't see a codebook, details about the data collection effort, etc.

dplyr 1.2.0 was released last week and since I use {dplyr} a lot in my work, I wanted to take some time to try some of the new functions.
This post provides some supplemental examples of the new functions, beyond what is provided in the new Posit materials.

Do you all have a need to encrypt files you generate before sending? I’ve been working with honeycakefiles.com to protect files. Just seeing if there might be interest in an r package to use it to protect your files if I can get one put together (with permission of the company)?

Can anyone suggest a good guides for using lab notebooks? (Like the traditional pen and paper bench scientist ones, not computational). Like I want to know what you're expected to write down, how you capture and transform the really important stuff, how you refer back to them etc etc

"If a dataset is confusing to a human analyst, it will be opaque to a language model. If the logic behind a metric lives only in someone’s head, an AI agent has no way to recover it. In that sense, AI does not lower the bar for data quality—it raises it."
Lot of chatter about AI ready data and how the shape of data might be changing. It's not, but your data management skills need to be on steroids. #databs
AI-Ready Data Is Still Analytics-Ready Data

Okay #StatsSky, used simulateData in lavaan to generate a dataset for a class. Included a seed in the code but students get one of two datasets: (1) the same as me or (2) a second dataset that was different but is identical to everyone else in the class that didn't end up with dataset #1.
