In quality control, such as other statistical problems, we may confront imprecise concepts. One case is a situation in which specification limits are two fuzzy sets. In such a fuzzy environment, the product is not qualified with a two valued Boolean view, but to some degree depending on the quality level of the product and the strictness of the ...

New Nonparametric Confidence Intervals for the Youden Index

Journal of Biopharmaceutical Statistics, 2012
The Youden index, a main summary index for the receiver operating characteristic (ROC) curve, is a comprehensive measurement for the effectiveness of a diagnostic test. For a continuous-scale diagnostic test, the optimal cut point for positive disease is the cut point leading to the maximization of the sum of sensitivity and specificity.

Likelihood Based Confidence Intervals for the Tail Index

Extremes, 2002
Let \(X_{1},\ldots,X_{n}\) be i.i.d. observations with distribution function \(F\) satisfying \(\lim_{t\to\infty} [1-F(tx)]/[1-F(t)]= x^{-1/\gamma}\), for all \(x>0\), where the parameter \(1/\gamma>0\) is called tail index. This paper investigates two methods, namely the empirical likelihood method and a parametric likelihood method, for constructing ...

Bootstrap confidence intervals for the pareto index

Communications in Statistics - Theory and Methods, 2000
In the present paper we develop second-order theory using the subsample bootstrap in the context of Pareto index estimation. We show that the bootstrap is not second-order accurate, in the sense that it fails to correct the first term describing departure from the limit distribution.
