R Programming for Statistics and Data Science - Geometrical Representation

The video tutorial covers the basics of regressions, focusing on simple linear regression. It explains the regression line as the best fitting line through data points on an XY plane, and details the components of the regression equation, including B0 (intercept) and B1 (slope). The tutorial also discusses the error term epsilon and its point estimate, the residual. The video concludes with a preview of the next lesson, which will provide practical examples and how to implement them using R.

Describe the concept of residuals in the context of regression analysis.

How can you predict a Y value using the regression line?
