Box-Cox transformations

As you have learned you can improve the utility of a variable in a model by leveraging variable transformations like the Box-Cox transformation for positive variable values. For example, the Pokemon dataset poke_df contains several numeric variables of the characteristics of different Pokemon attributes. Two variables collected on defensive efficiency are defense and speed. Both are positive and do not contain zero.
