Abstract

We introduce a new power transformation family which is well defined on the whole real line and which is appropriate for reducing skewness and to approximate normality. It has properties similar to those of the Box–Cox transformation for positive variables. The large‐sample properties of the transformation are investigated in the contect of a single random sample.
