WebThe Box-Cox Transformations procedure is designed to determine an optimal transformation for Y while fitting a linear regression model. It is useful when the variability of Y changes as a function of X. Often, an appropriate transformation of Y both stabilizes the variance and makes the deviations around the model more normally distributed. Weba Box-Cox transformation.
