    Glad that has restarted this hot discussion on datamethods. I just posted a response that tries to generalize the question.

    Statistically, machine learning has poor modeling practices which should limit generalizability. It doesn't. Why? For tasks like image recognition, all humans on the ML team understand ground truth; in healthcare/science tasks, it won't be the same. We can expect lots of failure.

    It's a big stretch to put such a positive spin on the wastage of resources that occurs when the scientific pathway is led astray building upon results that can't be replicated.

    A+ beautiful, a grand achievement by it is wonderful to see Byrne on clean background, all the original copies I saw over the years all had extensive foxing. In my Envisioning Information, we fully rebuilt 2 Byrne pages, hand-separated colors for printing.

    I recreated Byrne's 1847 edition of Euclid's Elements including interactive diagrams, cross references, and a new poster of all the original illustrations: Plus an in-depth blog post on how it was made:

    Let me get this straight: Sears has $25 million laying around to pay out executives who ran the company into the ground, but doesn't have any money to give the thousands of workers they laid off severance pay?

    A couple days ago another team asked me to speak about Bayesian data analysis. I decided that instead of doing a nuts/bolts of how to fit/use Bayesian models, I would describe "Bayesian analysis: The Good Parts". <potentially controversial thread>

    Not that this is terribly surprising, but still an important message for all to hear.

    In the U.S., law enforcement officers kill more than 1,000 civilians each year. New research shows that people who live in states with high gun ownership are much more likely to be shot and killed by police than those in low-gun states
