Automatic Selection of Box Cox Transformation Parameter
description
An automatic selection of the Box Cox transformation parameter is estimated with two methods. Guerrero's (1993) method yields a lambda which minimizes the coefficient of variation for subseries of x. For method "loglik", the value of lambda is chosen to maximize the profile log likelihood of a linear model fitted to x. For non-seasonal data, a linear time trend is fitted while for seasonal data, a linear time trend with seasonal dummy variables is used.
