Why perform a Multiple Regression Analysis?

Y = f (x1, x2, x3, . . .xn)

 

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.

Why use the Advanced Pareto chart function?

To help prioritize your efforts to reduce/eliminate defects. The Pareto principle indicates that approximately 80% of process defects are caused by 20% of the problems. Separate the vital few from the useful many.   The SigmaXL function helps draw comparisons between similiar categories.
