9.2 Linear Regression If there is a \signi cant" linear correlation between two variables, the next step is to nd the equation of a line that \best" ts the data. Such an equation can be used for prediction: given a new x-value, this equation can predict the y-value that is consistent with the information known about the data.

Integer variables are also called dummy variables or indicator variables. Really what is happening here is the same concept as for multiple linear regression, the equation of a plane is being estimated. We only use the equation of the plane at integer values of \(d\), but mathematically the underlying plane is actually continuous.
