A stationary stochastic time series is generated by an ARMA(5,2) process which fluctuates around a positive constant mean subject to a random disturbance term. You are also given a sample of observations {1,2,3, ... ,} for it as well as the values of the coefficients that generated the ARMA(5,2) process. Write down the general form of the ARMA(5,2) process for described above, define each individual element of the equation and explain the properties of the disturbance term of the process.
