Linear — Models With R

A linear model is only as good as the assumptions it satisfies. R excels here by providing built-in diagnostic tools. A simple plot(model) command generates four critical visualizations:

Wrapping variables in log() or sqrt() directly within the model call. Beyond the Fit: Diagnostics and Validation Linear Models with R

These tools shift the focus from mere "prediction" to "inference," ensuring the model is a valid representation of the underlying population. Modern Enhancements: The Tidyverse and Beyond A linear model is only as good as
