Statistics for Data Science and Business Analysis - A Geometrical Representation of the Linear Regression Model

The video tutorial introduces the concept of a regression line, explaining how it is the best fitting line through data points on an XY plane. It covers plotting the regression line using a regression equation and identifies observed values. The tutorial explains the roles of B0 and B1, where B0 is the intercept and B1 is the slope, indicating how Y changes with X. It discusses the error term epsilon and its point estimate, the residual. The video also explains how to find Y hat, the predicted value, by drawing a perpendicular from an observed point to the regression line. The lesson concludes with a preview of the next session.

Describe the relationship between Y hat and the regression line.
