Post-publication reviewing - some reflections
There is a pedagogic and pragmatic reason to consider post-publication reviews, which I believe are often dismissed. Science is an ever-correcting process, but also a slow process. Academia is a socia...

#rstats #dataviz Q: Does anyone have any code they can share for easily making a plot like this (sensitivity to priors for your model)?
That's why you need things lkle this (this comes from a paper that reported positive results. Some of them are clearly driven by the prior)

I used to be proud that I know how to use the em-dash, but now I worry when I do ppl will think "he clearly used an LLM because his 1st language isn't English!" 🙃
the internet has decided that em-dashes are a hallmark of llm writing, which is *extremely* annoying to me, as someone who uses em-dashes all the time.
dear internet please consider the possibility that LLMs use em-dashes a lot because they're, like, good

Maybe if statisticians started every sentence with "Yes, you are right. Let me do that for you"
The advances we've made in statistics, experimental study design, and causal inference over the past century are remarkably useful for understanding our world. But there is never been a push to make people use them like we are seeing with generative AI. Perhaps take a moment to consider why.
