Question

Consider an AR(2) model:

STEPS;
-Write the equation of the AR(2) model
- Determine the model based on the delay operator.
- Find the expected value of the model
- Find the variance of the model.
- Find the covariances associated with 1,2, and s steps.
- Find the associated correlation indices of 1,2, and s steps.
- Assume that information is available up to time $h$ and the function that contains the accumulated information f(h, h-1,……), determine the forecasts and the error associated with 1,2, and s steps.
- Assume that there is an initial value of the returns, denoted by $r_0$, and we have the AR(2) model at time rt, convert the AR(2) model into its equivalent MA(t)
