Dive into a comprehensive 27-minute video tutorial that clearly explains linear regression concepts. Learn about fitting lines to data using least squares, understanding R-squared, and its application in multivariable models. Explore why adding variables never reduces R-squared and how to calculate p-values for R-squared using the F-distribution. Gain insights into key statistical concepts with practical examples and clear explanations, perfect for both beginners and those looking to refresh their knowledge of linear regression techniques.
