Table C.4: Out-<strong>of</strong>-sample mean absolute errors (100 samples).<br />
This table reports the estimated out-<strong>of</strong>-sample MAE (×10 2 ) for the eighteen DJ Stoxx sectors.<br />
For each sector i, figures <strong>in</strong> parentheses denote the relative rank <strong>of</strong> a model’s MAE, where the<br />
model with the smallest MAE ranks first.<br />
