Re: Everything is a linear model
#2I find it irritating that the article mentions repeated measures, but does not try them, much less a mixed effects model. Yes, they are linear models with more parameters, but doing it in lm would be a special kind of madness

#4I thought nonlinearity was very important to be able to make a larger model better than a smaller one? Like so important that tom7 made a half-joke demo with it: https://yewtu.be/watch?v=Ae9EKCyI1xU

Linear models don’t need everything to be linear.

Linear models don’t need everything to be linear.
I presume you are implying that linear model only mandates linear relationship between predictor and regression coefficients?

Here is the Python port of test-as-linear developed by George Ho (eigenfoo):
https://github.com/minireference/tests-as-linear/blob/bugfix...
I'm linking to my fork of it because I've added some fixes and filled in some of the missing parts (e.g. Welch's t-test).

I read this article when I was in grad school 5 years ago. Absolutely love it and talk about it to this day.
It really makes me frustrated about the ways I was introduced to statistics: brute force memorization of seeming arbitrary formulas.

#9Hmm...I thought everything was an Eigenfunction.

Well, you can create a non-linear model by piece-wise combining multiple linear models.
The famous ReLU non-linearity is just that - two linear functions joined.
