WebJan 9, 2014 · @N-Wouda. I still think adding support for box-cox and similar transformation is of practical importance and should be added. We also have a new PR, #2892, that includes box-cox transformation in a new group of time series models. I never looked at box-cox in the context of time series forecasting, so I read Guerrero today, and WebJul 25, 2016 · The Box-Cox transform is given by: y = (x**lmbda - 1) / lmbda, for lmbda > 0 log (x), for lmbda = 0. boxcox requires the input data to be positive. Sometimes a Box-Cox transformation provides a shift parameter to achieve this; boxcox does not. Such a shift parameter is equivalent to adding a positive constant to x before calling boxcox. food prices increase australia
