Multiple linear regression
Whenever we have more than one input feature and want to build a linear regression model, we are in the realm of multiple linear regression. The general equation for a multiple linear regression model with k input features is:
Our assumptions about the model and about the error component ε remain the same as with simple linear regression, remembering that, as we now have more than one input feature, we assume that these are independent of each other. Instead of using simulated data to demonstrate multiple linear regression, we will analyze two real-world datasets.
