摘要
A computer program written in SAS(R) code for the Box-Cox family of power transformations is presented. The purpose of the program is to suggest a power transformation for the positive continuous response variables in only regression and ANOVA models. A brief overview of data transformation in regression and analysis of variance is given. An example using real data from the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program/Estuaries (EMAP-E) illustrates the use of the program.
