Definition / notes:	Definition: The Box-Cox transformation, below, can be applied to a regressor, a combination of regressors, and/or to the dependent variable in a regression. The objective of doing so is usually to make the residuals of the regression more homoskedastic and closer to a normal distribution: y(l) = ((y^L) - 1) / l for l not equal to zero y(l)=log(y)L=0 Box and Cox (1964) developed the transformation. Estimation of any Box-Cox parameters is by maximum likelihood. Box and Cox (1964) offered an example in which the data had the form of survival times but the underlying biological structure was of hazard rates, and the transformation identified this. http://economics.about.com/cs/economicsglossary/g/box_cox.htm
