To investigate the possibility to obtain normal distributed residuals by using the Box-Cox transformation a procedure has been implemented that is complementary to the use of the QQ-plot using the checkbox “Versus Normal Distribution” on the Dialog window of an ordinary output chart. After making any QQ plot the transformation can be applied by a click on the button Redesign Chart. By opening the tab sheet called Box Cox Transformation the Transformation can be turned on and various values on the coefficient in the transformation can be applied.
