Suppose that the daily log return of a security follows the model: rt =0.01+0.2rt-2+et, where e is a white noise series with mean zero and variance 0.02. Compute the 1-step and 2-step ahead forecasts of the return series at the forecast origin t=100. What are the associated standard deviations of the forecast errors?

Suppose the simple return of a monthly bond index follows the MA (1) model: r_t = a_t - 0.2a_t-1 We know the standard deviation of the white noise sigma = 0.025. Assume that a_100 = 0.01. Calculate the value of the 1-step and 2-step ahead forecast at time t = 100. Calculate the standard deviation of the associated forecast errors. Finally, compute the numerical values for the lag-1 and lag-2 autocorrelation of the return time series.
