Use the regression equation to describe the relationship between the response and the terms in the model. The regression equation is an algebraic representation of the regression model.
The regression equation with a continuous response and more than one term takes the following form:
y = b0 + b1X1 + b2X2 + ... + bkXk
In the regression equation, the letters represent the following:
- y is the continuous response variable
- b0 is the constant
- b1, b2, ..., bk are the coefficients
- X1, X2, ..., Xk are the values of the terms
