摘要：
Power transformations for achieving distributional symmetry are discussed. Estimates of the transformation power are based on general measures of symmetry. They are consistent and asymtotically normal. Use of the skewness coefficient as a measure of symmetry is optimal in an important special case. The methods are compared to the likelihood methods of Box et Cox (1964) and alternative methods of Hinkley. The Box-Cox method or a robust adaptation of it (Carroll, 1980; Bickel et Doksum, 1981) is generally the most suitable method.
