Annex 4 Results <strong>of</strong> diagnostic tests <strong>of</strong> issuing cost model<br />
A4.1 Normality <strong>of</strong> residuals<br />
The residuals were found to be approximately normal. There was little evidence <strong>of</strong> deviation from<br />
normality on the basis <strong>of</strong> inspection <strong>of</strong> the st<strong>and</strong>ardised normal probability plot.<br />

Empirical P[i] = i/(N+1)<br />
A4.2 Multi-collinearity<br />
The hypothesis that the estimated coefficients were stable <strong>and</strong> st<strong>and</strong>ard errors were not inflated is<br />
supported by variance inflation factors, which were mostly within the st<strong>and</strong>ard b<strong>and</strong> <strong>of</strong> tolerance<br />
(i.e. greater than 0.1), suggesting that the estimation results are robust to multicollinearity.
