Likelihood Based Inference on the Box-Cox Family of
SAS and Matlab Programs
Box and Cox (1964) proposed a parametric family of power
transformations of the data to reduce problems with non-normality and
heteroscedasticity. This paper presents programs in SAS and MATLAB to
compute the MLE and to compute approximate confidence intervals for the
Box-Cox transformation parameter.
