PSS propose a bound testing procedure. It involves just ardl bound testing in stata forex single-equation set-up, making it simple to implement and ardl test in stata forex.
Different variables can be assigned different lag-lengths as they enter the model. 1 to p ,and 0 to q1, 0 to q2, 0 to q3 and 0 to q4 respectively. We need to select the appropriate values for maximum lags, p, q1, q2, q3 and q4. The smaller the value of an information criterion the better the results. The rejection implies that we have a long-run relationship.

Also, if yt contains stochastic trend, we introduce a time trend t in equation 1. 2 above and test for the unit root. The null hypothesis is one of series contain stochastic trend against an alternative of trend stationarity.
