The Box-Cox transformation is defined as BC (y) = (y^lambda - 1)/lambda (and as log (y) for lambda==0 ). This transformation is not generally well-defined for negative y values (because it requires raising negative values to a power, which generates complex values in most cases). The car package provides similar transformations that ... WebDec 23, 2024 · The boxcox transformation is used for transforming the non-normally distributed data into normally distributed data. This is important as normality is an important assumption for many statistical techniques. This transformation works by finding a lambda value λ, which helps transform the data to normality.
