A new family of power transformations to improve normality or symmetry. (English) Zbl 1028.62010
Summary: 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 context of a single random sample.
