A Fast, High-Precision Implementation of the Univariate One-Parameter Box-Cox Transformation Using the Golden Section Search in SAS/IML®
Abstract
The one-parameter Box-Cox transformation is implemented using the golden section search algorithm in SAS/IML®. This code quickly produces the optimal value of the transformation to the user-specified parameter. It is presented in the form of a macro which has been tested using The SAS System for Windows®, releases 6.12 and 8.2. Changes to the SAS/IML® code are also presented for Schlesselman’s data-independent version of the Box-Cox transformation.
