This, raises the question, what is “an effect”?

1.1 This text is about using linear models to estimate treatment effects and the uncertainty in our estimates.

1 Analyzing experimental data with a linear model.

including mapping between linear models and classical tests.

Why bother with linear models – aren’t t-tests and ANOVA good enough?.
