Nettet1. Linear models. A linear model is a model for a continuous outcome Y of the form. Y = β 0 + β 1 X 1 + β 2 X 2 + ⋯ + β p X p + ϵ. The covariates X can be: a continuous variable (age, weight, temperature, etc.) Dummy variables coding a categorical covariate (more later) The β ’s are unknown parameters to be estimated. Nettet27. mai 2024 · There are five parameters, do d f 1 = 4. Then it is given that d f 2 = 37. d f 2 = n − p, so n = d f 2 + p = 37 + 5 = 42. Now we go to the R a d j 2 equation and plug in these values. The algebra shows that R 2 = 0.9016341463414634. A comment by whuber mentioned that you can relate the F-stat to R 2, too.
