Because some series contain negative raw data, and data is normalized by MinMax. Can VECM be used after second-order difference where the series are stationary? If can, whether the number of lagged difference is the p-1 or p-2 through VAR(p)?
Can second order differences stationary series be estimated via VECM model without considering support from economic theory?
