Thereafter, the factor analysis was cross-validated in the reference sample to evaluate if the factor structure was stable during other conditions, i.e. in the nursing students.
By using DVR parameters in five regions (frontal, parietal, medial temporal, lateral temporal, and posterior cingulate), excellent discrimination between control subjects and AD patients was achieved, with 100% sensitivity, specificity and classification accuracy (cross-validated 95%), using either reference regions (Table 2).
Cross-validation indicates that vigiRank is not over-fitted to sampling variability of the reference dataset: the mean cross-validated AUC is marginally below that for the reference dataset as a whole, the selected predictors and their coefficients are remarkably consistent over the five cross-validation iterations, and vigiRank consistently outperforms IC025 over all iterations.
The analyte concentrations determined by cross-validated PLS regression and the reference concentrations found for the different samples drawn from the two fermentations are shown in Fig. 5.
The classifier results are cross-validated using hold out cross-validation.
Additionally, midgut proteins were identified and annotated by mass spectrometry with public databases and the in-house built transcriptome database as references and results were cross-validated.
Model significance was assessed using a cross-validated ANOVA based on seven-fold cross validation.
We provide results for overfitted CART O and cross-validated CART C, where 10-fold cross-validation was applied.
We used 20-fold cross validations to determine tuning parameter λ yielding minimum cross-validated errors.
Results were cross-validated splitting the total sample randomly and using the cross-validation index.
The assay is calibrated using a standard curve that has been cross-validated to known quantities of total IgE in the WHO 75/502 IgE International Reference Preparation.
