On Distributions and Their Transformation to Normality
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1969 Summary Further consideration is given to a family of power transformations discussed by Box and Cox (1964). It is shown that this family of transformations can be useful even in situations where no power transformation can produce normality exactly. The precision of estimation of the transformation parameter is also discussed.
