WebMay 31, 2024 · The Box-Cox transformation is a generalization of the power family of transformations, and it is defined by: where X is the variable and λ is the transformation parameter. The Box-Cox transformation can be used for transformations that we discussed before, including no transformation (λ = 1), the logarithm (λ = 0), the … WebFor the Box-Cox transformation, a λ value of 1 is equivalent to using the original data. Therefore, if the confidence interval for the optimal λ includes 1, then no transformation is necessary. In this example, the 95% confidence interval for λ (−2.49 to 0.84) does not include 1, so a transformation is appropriate.
