Extension of the pool-adjacent-violators algorithm
Communications in Statistics - Theory and Methods, 1991The pool-adjacent-violators algorithm (PAVA) is an efficient algorithm which converges in a finite number of steps. However, it has been applicable so far only in isotonic regression with the simple order. This report extends its applicability to other quadratic programming problems, including certain one-sided multivariate testing problems and concave

Pool Adjacent Violators Based Biometric Rank Level Fusion [PDF]
Biometrics and Electronic Signatures, 2017 We propose a new method in rank level fusion for biometric identification. Our method is based on the pool adjacent violators (PAV) algorithm after the ranks have been transformed to the approximated scores.We then show that our method outperforms ...

Lifetime Data Analysis, 2013
A likelihood based approach to obtaining non-parametric estimates of the failure time distribution is developed for the copula based model of Wang et al. (Lifetime Data Anal 18:434-445, 2012) for current status data under dependent observation. Maximization of the likelihood involves a generalized pool-adjacent violators algorithm.

The validity of the “Pool-Adjacent-Violator” algorithm
Statistics & Probability Letters, 1988The purpose of this paper is to show that if G is a positive definite symmetric real matrix, the solution to minimize \((g-x)'G(g-x)\) subject to \(x'A\geq 0\) can be determined through the pool-adjacent-violator (PAV) algorithm if and only if the restrictions cone, \(\hat A,\) is acute.

Semiparametric probit regression model with misclassified current status data
Statistics in Medicine, 2023Current status data arise when each subject under study is examined only once at an observation time, and one only knows the failure status of the event of interest at the observation time rather than the exact failure time.

A new approach for credit scoring by directly maximizing the Kolmogorov-Smirnov statistic
Computational Statistics & Data Analysis, 2019Credit scoring plays a critical role in many areas such as business, finance, engineering and health. The Kolmogorov–Smirnov statistic is one of the most important performance evaluation criteria for scoring methods and has been widely used in practice ...
