Let's begin our triple W session with linear regression first.

What is linear regression?
It is the traditional and most-used regression analysis. It is studied rigorously and used widely for practical purposes. Linear regression is a method for determining the relationship between a dependent variable (y) and one or more independent variables (x). This derived relationship can be used to predict an unexplained y from observed x's. Mathematically, if x is an independent variable (commonly known as the predictor) and y is a dependent variable (also known as the target), the relationship is expressed as follows:
Where m is the slope of line, b is the intercept of the best-fit regression line, and...
