Y = f (x₁, x₂, x₃, . . .x_n)

To detemine which input or process variables (Xs) affect your output (Y).  Multiple regression helps find the source of  most of your variation in the process.  If you know the primary sources of variation you can reduce or eliminate the variation.  The demo below shows that Responsiveness to Calls and Ease of Communication account for 90% of the variation.  This tells you that your improvement efforts should center around these factors to have the greatest impact on Overall Satisfaction.
