This means that all variables have stationary
qualifications at First Differencing include FFB_F Price,
CPO_T Price, CPO_M Price, CPO_L Price, B100 Price,
RPO_T Price, RPO_M Price, Cooking Oil Price,
GDP_Percapita, SBO_W Price, RSS_F Price and QFFB_F.
The value from the test was conducted by considering the tautest value is greater than the tau-critical. The researcher takes
the first difference to calculate the equilibrium relationship
and found that variables have long-term equilibrium
relationships. The researcher uses that suitable variable to
build ARIMAX Model.
