Abstract
This paper derives Lagrange multiplier tests based on artificial double length regressions (DLR) to jointly test for differenced linear or loglinear models with no heteroskedasticity or autocorrelation against a more general differenced Box-Cox model with heteroskedasticity or autocorrelation. These tests are easy to implement and are illustrated using an empirical example.
