Only unknowns are the regression coefficients so to specify the equation, we need to assign values The regression coefficients areī 0, b 1, and b 2. Which are denoted by x 1 and x 2, respectively. The independent variables are IQ and study hours, In this equation, ŷ is the predicted test score. Since we have two independent variables, the equation takes the following form: The first task in our analysis is to define a linear, least-squares regression equation to predict test score,īased on IQ and study hours. Let's review the output produced by Excel and see how it addresses each task.
