Question

Using the data file Housing Starts, estimate autoregressive models of orders 1 through 4 . Use the method of this section to test the hypothesis that the order of the auto regression is $p-1$ against the alternative that the order is $p$, with a significance level of $10 \%$. Select one of these models, and calculate forecasts of housing starts for the next 5 years. Draw a time plot showing the original observations together with the forecasts. Would different forecasts result if a significance level of $5 \%$ was used for the tests of autoregressive order?
