As a tool for data analysis, the ACE procedure provides graphical output to indicate a need for transformations as well as to guide in their choice. If a particular plot suggests a familiar functional form for a transformation, then the data can be pre-transformed using this functional form and the ACE algorithm can be rerun.
Wang suggests that the [[Power transform|Box-Cox transform]], a parametric approach, is a special case of ACE.<ref>Wang, D., Murphy, M. 2005. Identifying Nonlinear Relationships in Regression using the ACE Algorithm. Journal of Applied Statistics. 32(3) 243-258.</ref>
