Using leave-one-out cross-validation, the accuracy, sensitivity, specificity, and both false positive and false negative ratios of the proposed method were found to be 0.97, 0.98, 0.96, 0.04, and 0.02, respectively.
Our experiments on five highly imbalanced splice site datasets, with positive to negative ratios of 1-to-99, showed that the ensemble-based semi-supervised approaches represent a good choice, even when the amount of labeled data consists of less than 1% of all training data.
Where price is included as an attribute, WTP for a change in attribute levels may be estimated as the negative ratio of the attribute and price parameters.
The application of D-dimer testing for suspected PE in this study population had a sensitivity of 100%9595% CI, 73 100%), specificity of 42% (95% CI, 31 53%) and a likelihood negative ratio of 0. None of the clinical variables were significant predictors of PE according to regression analyses.
The public's valuation of innovation characteristics, i.e., marginal willingness to pay (WTP), is then given by the (negative) ratio of the attribute parameter to the parameter on the cost of innovations.
The intervention arm smears were either screened or stored, depending on the primary hrHPV test result: if the hrHPV test resulted negative (ratio of the relative light units (rlu ratio) less than 1.00), the smear was stored unscreened; if positive (rlu ratio ⩾1.00), the cytological analysis was carried out.
Recent studies have tried to explore this effect, including one by positive psychology researcher Barbara Fredrickson, which concluded we need a 3 1 positive-to-negative ratio of thoughts to free our minds from the tar-paper effect of negative thinking.
The positive-to-negative ratio of the 'effect' category was calculated (per source, 'type of article' and 'age group' categories).
The H. pylori-associated overmethylation rate was calculated using the H. pylori-positive-to-negative ratio of each transitional-CpG-overmethylation rate.
Positive ratios represent more expression of respective genes in dCINs compared to MNs and negative ratios more expression of respective genes in MNs compared to dCINs.
In a patient-based analysis, sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios of CTCA were 91%, 50 %, 68 %, 83 1.82, and 0.18, respectively.
