A Modified Family of Power Transformations
A modified family of power transformation, called the Dual Power Transformation, is proposed, which overcomes the truncation problem of the Box-Cox power transformation. The new transformation possesses properties similar to those of the Box-Cox power transformation. It generates a rich family of di...
