What will I learn?

The R2 Course provides a quick, hands-on way to master linear regression, R-squared, and adjusted R-squared for making real-world decisions. You'll set up a practical retail sales study, build and compare simple and multiple models, perform diagnostics, implement fixes, and produce clear, reproducible reports that turn technical results into strong, data-backed advice for stakeholders.
