Efficient vs. structured biodiversity inventories: reptiles in a Mexican dry scrubland as a case study [PDF]
Animal Biodiversity and Conservation, 2018 Many sampling methods allow the study of species richness and diversity in biological communities, but it is not known whether a single method can determine both the number and diversity of species in an unbiased and efficient way. Here we assess whether

Smoothing-inspired lack-of-fit tests based on ranks
, 2008 A rank-based test of the null hypothesis that a regressor has no effect on a response variable is proposed and analyzed. This test is identical in structure to the order selection test but with the raw data replaced by ranks. The test is nonparametric in

A constructive and unifying framework for zero-bit watermarking [PDF]
, 2006 In the watermark detection scenario, also known as zero-bit watermarking, a watermark, carrying no hidden message, is inserted in content. The watermark detector checks for the presence of this particular weak signal in content. The article looks at this

A Generalization of the Sukhatme's Test for Two-Sample Scale Problem
Journal of Statistical Theory and Applications (JSTA)In this paper, we present nonparametric tests for the two-sample scale problem. The proposed tests include as special case the B.V. Sukhatme, Ann. Math. Stat. 28 (1957), 188–194, and J.V. Deshpande, K. Kusum, Aust. J. Stat. 26 (1984), 16–24 tests.

Tests for Two-Sample Location Problem Based on Subsample Quantiles [PDF]
, 2014 This paper presents a new class of test procedures for two-sample location problem based on subsample quantiles. The class includes Mann-Whitney test as a special case. The asymptotic normality of the class of tests proposed is established.

Pitman Efficiencies of Kolmogorov-Smirnov Tests
The Annals of Mathematical Statistics, 1971 A comparison, by means of Pitman asymptotic efficiency, is made between the Kolmogorov-Smirnov test and the locally most powerful rank and the locally asymptotically most powerful (Neyman) test for testing two-sided shifts in the two-sample problem under the assumption that the true distribution is different from the one assumed.

Minimax Estimation of Nonregular Parameters and Discontinuity in Minimax Risk
, 2014 When a parameter of interest is nondifferentiable in the probability, the existing theory of semiparametric efficient estimation is not applicable, as it does not have an influence function.

, 2011 Pulsation is believed to be the leading cause of dusty mass loss from Asymptotic Giant Branch (AGB) stars. We present a temporal study of T Cep, a long-period Mira variable, using seven ISO SWS spectra, covering a 16-month period over a single pulsation ...

Agribusiness, EarlyView.ABSTRACT This study investigates how consumer taste and brand equity perceptions shape the acceptance of plant‐based milk products. Using a blind/informed tasting experiment, we evaluated consumers' willingness to buy (WTB) and taste perception of a plant‐based milk alternative produced by a traditional dairy brand, compared with competing plant‐based ...

Intelligent Operator‐Independent Flexibility in Robotic Non‐Destructive Evaluation
Advanced Intelligent Systems, EarlyView.Non‐destructive evaluation of high‐value components remains a manufacturing bottleneck due to rigid robotic calibration and fixturing. This study presents a flexible, adaptable system integrating 3D vision and force‐position control with a collaborative KUKA LBR robot. The geometry‐agnostic system enables pose‐independent ultrasonic inspection, detects
