Decoding Emotional Signatures of Ethical Ads: An Analysis of Actor‐Viewer Synchrony
Journal of Consumer Behaviour, Volume 25, Issue 3, Page 1061-1077, May 2026.ABSTRACT We examine whether ethical advertisements differ from conventional ads in their on‐screen emotional signatures and whether those signatures transfer to actor‐viewer synchrony. Study 1 analyses 138 professionally produced YouTube ads using Automated Facial Expression Recognition (AFER) and Convolutional Neural Networks (CNN) to quantify actor ...

Statistical Change Detection by the Pool Adjacent Violators Algorithm
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2011In this paper, we present a statistical change detection approach aimed at being robust with respect to the main disturbance factors acting in real-world applications such as illumination changes, camera gain and exposure variations, noise. We rely on modeling the effects of disturbance factors on images as locally order-preserving transformations of ...

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

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.

AbstractPersonalized medicine allows individuals to choose the best fit of their treatments based on their characteristics through an individualized treatment regime. In this paper, we develop a pool adjacent violators algorithm–assisted learning method to find the optimal individualized treatment regime under the monotone single‐index outcome gain ...

The National Hockey League Entry Draft, 1969–1995 [PDF]
The American Statistician, 2001 We use data on the National Hockey League Entry Draft and subsequent performances of the players to predict performance as a function of the players position, year, and overall rank in the draft. This is done by inequality-constrained least squares using a variation of the 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.
