In this video tutorial I develop an inituitive understanding of ordinary least squares (OLS) and how it pertains to finding a quadratic equation, a cubic equation, and a linear equation given three point in the plane.
Developing an intuition for OLS requires understanding of the column space of a matrix and how to project a vector onto that space. This is done through a simple schematic and I use Julia code to show just how easy it is to calculate using ordinary least squares.
