- Simple linear regression formula. As detailed above, the formula for simple linear regression is: or. for each data point - Simple linear regression model – worked example. Let’s say we are ...

Multiple Linear Regression: Multiple linear regression describes the correlation between two or more independent variables and a dependent variable, also using a straight regression line.

Simple linear regression relates two variables (X and Y) with a straight line ... Then, each of those differences is squared. Lastly, all of the squared figures are added together.

In simple linear regression 1, ... Figure 1: The results of multiple linear regression depend on the correlation of the predictors, as measured here by the Pearson correlation coefficient r (ref. 2).

Multiple linear regression is a more specific calculation than simple linear regression. For straight-forward relationships, simple linear regression may easily capture the relationship between ...
