Radicalités positives

False positives in cancer epidemiology.

BACKGROUND A recent attempt to estimate the false-positive rate for cancer epidemiology studies is based on agents in International Agency for Research on Cancer (IARC) category 3 (agent not classifiable as to its carcinogenicity to humans) in the IARC Monographs Program. METHODS The estimation method is critiqued regarding biases caused by its reliance on the IARC classification criteria for...

Group Testing for Consecutive Positives*

Strategies for adaptive and nonadaptive group testing are developed when the items are linearly ordered and the positive items form a consecutive subset of all items.

Accurate decisions in an uncertain world: collective cognition increases true positives while decreasing false positives.

In a wide range of contexts, including predator avoidance, medical decision-making and security screening, decision accuracy is fundamentally constrained by the trade-off between true and false positives. Increased true positives are possible only at the cost of increased false positives; conversely, decreased false positives are associated with decreased true positives. We use an integrated th...

Improbability Filtering for Rejecting False Positives

In this paper we describe a novel approach, called improbability filtering, to rejecting false-positive observations from degrading the tracking performance of an Extended Kalman-Bucy fdter. False-positives, incorrect observations reported with a high confidence, are a form of non-Gaussian white noise and therefore degrade the tracking performance of an Extended Kalman-Bucy Filter. Improbabilit...
