Stop Memorizing Formulas: Visualize Linear Regression Geometrically - Lesson 006 - ESL

We will give a geometric interpretation of the ordinary least squares method of deriving beta coefficients for a linear regression model. In this lesson you will learn that how via simple vector geometry one can arrive at the same results as we did via OLS method.
