In statistical quality control, the regression control chart allows for monitoring a change in a process where two or more variables are correlated. The change in a dependent variable can be detected and compensatory change in the independent variable can be recommended. Examples from the Post Office Department[clarification needed] provide an application of such models.[1]

Difference

[edit]

Regression control chart differs from a traditional control chart in four main aspects:

  • It is designed to control a varying (rather than a constant) average.
  • The control limit lines are parallel to the regression line rather than the horizontal line.
  • The computations here are much more complex.
  • It is appropriate for use in more complex situations. [1]
