Linear Regression - A Friendly Introduction

Explore linear regression through a visually-oriented introduction that minimizes complex mathematics. Begin with an examination of housing prices to illustrate the concept. Learn how to manipulate a line by changing its slope (rotation) and y-intercept (translation). Discover the linear regression algorithm and understand the importance of positive and negative distances. Delve into the "one rule to rule them all" principle, and compare square error and absolute error methods. Conclude with an introduction to the absolute trick and a preview of a three-part video series on the topic. This approachable explanation of linear regression is ideal for those seeking a foundational understanding without the need for advanced calculus or linear algebra.
