Information Threshold, Bayesian Inference and Decision-Making
Jacques Balayla
We define the information threshold as the point of maximum curvature in the prior vs. posterior Bayesian curve, both of which are described as a function of the true positive and…
Prevalence Threshold and bounds in the Accuracy of Binary Classification Systems
Jacques Balayla
The accuracy of binary classification systems is defined as the proportion of correct predictions - both positive and negative - made by a classification model or computational alg…
The SIR-P Model: An Illustration of the Screening Paradox
Jacques Balayla
In previous work by this author, the screening paradox - the loss of predictive power of screening tests over time - was mathematically formalized using Bayesian theory. Where…
Theorems on the Geometric Definition of the Positive Likelihood Ratio (LR+)
Jacques Balayla
From the fundamental theorem of screening (FTS) we obtain the following mathematical relationship relaying the pre-test probability of disease to the positive predictive value…
On the Formalism of The Screening Paradox
Jacques Balayla
Bayes' Theorem imposes inevitable limitations on the accuracy of screening tests by tying the test's predictive value to the disease prevalence. The aforementioned limitation is in…
Derivation of Generalized Equations for the Predictive Value of Sequential Screening Tests
Jacques Balayla
Using Bayes' Theorem, we derive generalized equations to determine the positive and negative predictive value of screening tests undertaken sequentially. Where a is the sensitivity…
Bayesian Updating and Sequential Testing: Overcoming Inferential Limitations of Screening Tests
Jacques Balayla
Bayes' Theorem confers inherent limitations on the accuracy of screening tests as a function of disease prevalence. We have shown in previous work that a testing system can tolerat…
Prevalence Threshold and the Geometry of Screening Curves
Jacques Balayla
The relationship between a screening tests' positive predictive value, , and its target prevalence, , is proportional - though not linear in all but a special case. In conseq…
The Fourier Evaluation of Tracings and Acidosis in Labor: the FETAL Technique
Jacques Balayla
Adequate fetal and neonatal development depend upon the presence of a normal acid-base environment during pregnancy and the smooth transition from intra-uterine to extra-uterine li…
The Individual Impact Index () Statistic: A Novel Article-Level Citation Metric
Jacques Balayla
Citation metrics are analytic measures used to evaluate the usage, impact and dissemination of scientific research. Traditionally, citation metrics have been independently measured…
