Box-Cox transformation

There appears to be non-constant variance, and a Box-Cox transformation might help.

Economists often characterize production relationships by some variant of the Box-Cox transformation.

The data can be found via the classic data sets page and there is some discussion in the article on the Box-Cox transformation.

Note that although Box-Cox transformations can make big improvements in model fit, there are some issues that the transformation cannot help with.

His name is associated with results in statistics such as Box-Jenkins models, Box-Cox transformations, Box-Behnken designs, and others.

In statistics, the Box-Cox distribution (also known as the power-normal distribution) is the distribution of a random variable X for which the Box-Cox transformation on X follows a truncated normal distribution.
