View source: R/boxcoxfr.R. Description. boxcoxfr performs Box-Cox transformation for one-way ANOVA. It is useful to use if the normality or/and the homogenity of variance is/are not satisfied while comparing two or more groups. Box-Cox Transformation for Simple Linear Regression Introduction This procedure finds the appropriate Box-Cox power transformation (1964) for a dataset containing a pair of variables that are to be analyzed by simple linear regression .

The Box-Cox transformation of the variable $$x$$ is also indexed by $$λ$$, and is defined as $x' = \dfrac{x^\lambda-1}{\lambda} \label{eq1}$ At first glance, although the formula in Equation \ref{eq1} is a scaled version of the Tukey transformation $$x^\lambda$$, this transformation does not appear to be the same as the Tukey formula in Equation (2). Ideally, a data transformation is chosen based on knowledge of the process generating the data, as well as graphical tools such as quantile-quantile plots and histograms. Box and Cox (1964) presented a formalized method for deciding on a data transformation. Box Cox transformation shifts the data to a root of the data using lambda:-1< lambda <1 (e.g., 3.01^0.5) or ln(3.01) if lambda = 0.

The regression model is therefore used to fit the transformed response. The Box-Cox power transformation can be used to transform a variable for other various purposes.
