I am not anti LLM across the board. But if your use case starts with the necessary assumption that the model is a vessel of all human knowledge, then you are consulting an oracle not doing scientific research.

"more creative errors, like thinking that exponentiation of the coefficient from a linear regression with a log-transformed outcome results in an odds-ratio."
Oh, my. I was not prepared for this. The link points to Twitter, so I can't see the original. That's probably better

You forgot to mention that all files should be in a git repo hosted on GitHub or even better - on your own personal server

Yep. You don't want to end up with scientific notation for your coefficient estimates because they are too small or too large. Not only because it's not easy to read for some people, but also because it can bring up numerical issues in estimation

I guess we end up with my most frequent response to any stats-related question - "it depends". In this case, it depends on the measurement scale of the DV, on the range of Age in the sample, and the specific goal of the analysis (e.g., what hypothesis needs to be tested)

Let's say the outcome is yearly income. This income can be measured in EUR, or it can be measured in another currency (i.e., HUF), with an exchange rate of 1 HUF = 0.0025 EUR, or 1 EUR = 400 HUF. When using the DV measured in HUF, rescaling age might not be needed.
