| In this technical paper, an adapted cross-validation is described for this case. |
| With cluster sampling, standard cross-validation underestimates the generalization error rate, and is deficient for model selection. |
| Whatever algorithm is used, the key to producing a stable and robust calibration is to avoid over fitting, by using either a test set or some form of cross-validation to moderate the fitting process. |
| This map should not be used for operational water resource assessments without some form of local cross-validation. |
| In some cases, cross-validation includes multivariate analyses of survey data. |
| These are accompanied by skill maps, as obtained from cross-validation over a 39-year period. |
