The impact diagnostic test performance can be illustrated by estimation of predictive values, the probability of a tested individual having a given infection status condition on its test result.
HIV prevalence in the population being tested can affect test performance, particularly positive predictive value, the probability that a person actually has HIV given that he or she tests positive [7].
Earlier studies have shown that a low MMSE score is predictive for the probability of dropping out of a study.
The positive predictive value, the probability of the presence of progressive joint damage when hand BMD loss is present, was 39 of 168 (23%), whereas the negative predictive value, the probability of absence of progressive joint damage when hand BMD loss is absent, was 74 of 80 (93%).
We also noticed that fitness measures taken prior to extinction were not predictive of the probability of extinction in the following bottleneck.
Negative predictive value was the probability for any particular negative prediction (no hypovolaemia or no hypervolaemia) that the condition was indeed absent (true negative).
Positive predictive value was the probability for any particular positive prediction (hypovolaemia or hypervolaemia present) that it was correct (true positive).
The goal is to model the predictive probability of the concerning annotation terms T, giving the training set D, a prior KGP, and a test sample x, which can be expressed as p(T | D, x, KGP).
We compare the results of the SA method, the decision-theoretic method, the predictive probability method, and the posterior probability method.
Using logistic regression analysis, the authors calculated that the predictive probability of the presence of breast cancer was ≥ 80%, when levels of ADAM12 exceeded 40 arbitrary units [ 53].
