Box Cox Transformation Sas. In the cars data suppose that we want to fit a simple linear re-. PROC TRANSREG is run to find the Box-Cox transformation.
I think SAS is considering a generalization of the boxcoxy transformation in TRANSREG see example 6 of the procedure which is for fixed effects to an approach for a mixed-effects model. The Box-Cox transformation has the form This family of transformations of the positive dependent variable y is controlled by the parameter. Transformations linearly related to square root inverse quadratic cubic and so on are all special cases.

By default g 1. The parameter c can be used to rescale y so that it is strictly positive. Box-Cox transformations are used to find potentially nonlinear transformations of a dependent variable.
