Question:

Update the time series on the number of unemployed people looking for part-time work (Figure 7.13). Plot the time series. Compute the autocorrelation and partial autocorrelation functions. Which time series model would you entertain? Estimate the model and construct the 1-step-, 2-step-, and 3-step-ahead forecasts, their forecast errors, and the uncertainty associated with the forecasts.
