Chapter 3The goodness-of-fit is clearly better than <strong>in</strong> the fully determ<strong>in</strong>istic case: the AIC is smaller (-4.42<strong>in</strong>stead of -3.77) as well as the BIC (-4.29 <strong>in</strong>stead of -3.68).For all lags considered, the Box-Ljung test <strong>in</strong>dicates that the most important model assumption,i.e. <strong>in</strong>dependence, is satisfied, as we already noted on the basis of Figure 3.6.9 <strong>and</strong> <strong>in</strong> Table3.6.5.Step 6: Test of auxiliary residuals Go to the STAMP w<strong>in</strong>dow aga<strong>in</strong> <strong>and</strong> choose . In the Auxiliary residuals graphics w<strong>in</strong>dow select Irregular, Level residual,Index plot, Density, Histogram, Normal, QQ plot, Write normality tests, <strong>and</strong>Write values exceed<strong>in</strong>g (3.5).
