Linear Regression Equation Explained - Statistics By Jim
A linear regression equation describes the relationship between the independent variables (IVs) and the dependent variable (DV). It can also predict new values of the DV for the IV values you specify. In this post, we’ll explore the various parts of the regression line equation and understand how to interpret it using an example.
Least Squares Regression - Math is Fun
We can place the line "by eye": try to have the line as close as possible to all points, and a similar number of points above and below the line. But for better accuracy let's see how to calculate the line using Least Squares Regression. The Line. Our aim is to calculate the values m (slope) and b (y-intercept) in the equation of a line:
