      Following the new tools for spurious regression model of Phillips (1998), and the theoretical frame work of Hendry (1995, Chapter 3), we proposed the transformation of the variables in such a way so that the stochastic trend variance and correlation reduce in a standard level and the variables are cointegrated.
