Boxcox In R Example. Computes and optionally plots profile log-likelihoods for the parameter of the Box-Cox power family the Yeo-Johnson power family or for either of the parameters in a bcnPower family. Boxcox is a generic function used to compute the values of an objective for one or more Box-Cox power transformations or to compute an optimal power transformation based on a specified objective.
However a few steps are needed to extract the lambda value and transform the data set. Boxcox Power Transformation Description. Boxcox savings_model plotit TRUE lambda seq 05 15 by 01.
Computes and optionally plots profile log-likelihoods for the parameter of the Box-Cox power family the Yeo-Johnson power family or for either of the parameters in a bcnPower family.
Hide Comments Share Hide Toolbars. Boxcox savings_model plotit TRUE R automatically plots the log-Likelihood as a function of possible λ λ values. Library MASS boxcox yx plot 1y2x since the profile likelihood has a maximum near 2 But it really depends on what you mean by better fit to the data. Boxcox returns a lambda value.
