Score-Based Hypothesis Testing for Unnormalized Models
IEEE Access, 2022 Unnormalized statistical models play an important role in machine learning, statistics, and signal processing. In this paper, we derive a new hypothesis testing procedure for unnormalized models. Our approach is motivated by the success of score matching

Circulation, 2006 In most biomedical research, investigators hypothesize about the relationships of various factors, collect data to test those relationships, and try to draw conclusions about those relationships from the data collected. In many cases, investigators test relationships by comparing the average level of a factor between 2 groups or between 1 group and a ...

Entropy, 2016 The extraordinary success of physicists to find simple laws that explain many phenomena is beguiling. With the exception of quantum mechanics, it suggests a deterministic world in which theories are right or wrong, and the world is simple.

Medication-Wide Association Study Plus (MWAS+): A Proof of Concept Study on Drug Repurposing
Medical Sciences, 2022 The high cost and time for developing a new drug or repositioning a partially-developed drug has fueled interest in “repurposing” drugs. Drug repurposing is particularly of interest for Alzheimer’s disease (AD) or AD-related dementias (ADRD) because ...

Testing Environmental Kuznets Curve Hypothesis for N2O
İzmir İktisat Dergisi, 2021 N2O, one of the most harmful of greenhouse gases, causes great damage to the environment. Although it does not attract as much attention as CO2, policies to reduce the emission of this gas are of great importance for a sustainable environment and economy.

Test of no-effect hypothesis [PDF]
Afrika Statistika, 2009 Abstract. On se donne une suite de vecteurs al´eatoires (X1, Y1) , ..., (Xn, Yn) d´efinies sur le m`eme espace probabilis´e ( , A, P) . Apr`es avoir consid´er´e l’estimation de la fonction de regression r (x) , nous ´etudions le test d’hypoth`ese nulle“r (x) = cste”, c’est `a dire que X n’a pas d’effet en moyenne sur Y, dans deux situations o`u les ...

Hypothesis Testing With Rank Conditions in Phylogenetics
Frontiers in Genetics, 2021 A phylogenetic model of sequence evolution for a set of n taxa is a collection of probability distributions on the 4n possible site patterns that may be observed in their aligned DNA sequences. For a four-taxon model, one can arrange the entries of these

Statistical Hypothesis Testing for Asymmetric Tolerance Index
Applied Sciences, 2021 Many of the nominal-the-best quality characteristics of important machine tool components, such as inner or outer diameters, have asymmetric tolerances. An asymmetric tolerance index is a function for the average of the process and the standard deviation.

Testing the manifold hypothesis [PDF]
Journal of the American Mathematical Society, 2016 The hypothesis that high dimensional data tend to lie in the vicinity of a low dimensional manifold is the basis of manifold learning. The goal of this paper is to develop an algorithm (with accompanying complexity guarantees) for fitting a manifold to an unknown probability distribution supported in a separable Hilbert space, only using i.i.d samples ...

Testing the facsimile accommodation hypothesis
Acta Psychologica, 2022 Research has failed to find evidence for a genuineness effect: the idea that aesthetic experiences are better when looking at real artworks versus reproductions of those artworks.
