Repeated Out of Sample Fusion in
Interval Estimation of Small Tail Probabilities in Food Safety
ABSTRACT
In food safety and bio-surveillance in many cases it is desired to estimate the probability that a contaminant such as some insecticide or pesticide exceeds unsafe very high thresholds. The probability or chance in question is then very small. To estimate such a probability we need information about large values. However, in many cases the data do not contain information about exceedingly large contamination levels. A solution is suggested whereby more information about small tail probabilities is obtained by REPEATED FUSION of the real data with computer generated "fake" data. The method provides short, yet reliable, interval estimates from moderately large samples. An illustration is provided using exposure data from the National Health and Nutrition Examination Survey (NHANES).
