Box Cox. The basic idea behind this method is to find some value for λ such that the transformed data is as close to normally distributed as possible using the following formula. So if a statistical program supports these capabilities writing a macro for a Box-Cox normality plot should be feasible.
Feb 26 2010 The Box-Cox power transformation is not a guarantee for normality. The method checks for the smallest standard deviation. At the core of the Box Cox transformation is an exponent lambda λ which varies from -5 to 5.
Minitab will select the best mathematical function for this data transformation.
The Box-Cox transformation is a family of power transformations. The Box-Cox methodology and multiyear data were used to facilitate this comparison. Minitab will select the best mathematical function for this data transformation. Doksum 1981 studied consistency properties of the Box-Cox estimates of the transformation parameter in the.
