One method for calculating the validity of a screening instrument which takes into account ASD prevalence is Bayes Theorem.
To verify the method's potential use as an early warning system for human risk, we calculated the validity of the model-estimated risk map versus the raw incidence map from August 13 for predicting the case distribution for October 1, 2003.
To calculate the validity and reliability of a questionnaire to measure the quality of life in post-menopausal women.
We did not use a common database to calculate the validity, sensitivity, or specificity of the ICHD-3 beta criteria.
First univariate linear regression was applied to y and x, and then Cook's distance was calculated to estimate the validity of the data points.
If you wanted to, for instance, you could calculate the predictive validity of prowess at Scrabble, or the number of books a student reads in his senior year, or, more obviously, high-school grades.
A diffusion problem is calculated and the validity of the proposed model is shown.
However, although the tendency is the same, the results for these descriptors are in poor agreement between those calculated assuming the validity of the Koopmans' theorem, and those coming from energy differences.
Third, using a DSM-IV-TR criterion-defined delirium as gold standard, we used sensitivities (SE), specificities (SP), positive and negative predictive values (PPV and NPV respectively) and their confidence intervals and calculated the concurrent validity of each RADAR item and the RADAR scale as a whole.
The false negatives and the false positives, which are the amino acids detected as involved in a chemical interaction by other methods but not by GeminiDistances and the way around, respectively, are calculated as an estimate of the validity of the symmetrization.
