An uniformly superior exact multi-sample test procedure for homogeneity of variances under location-scale family of distributions.

Publication Type: Academic Journal

Source(s): Journal of Statistical Computation & Simulation. Dec2022, Vol. 92 Issue 18, p3931-3957. 27p.

Abstract: An exact test procedure based on the generalized variable approach for testing homogeneity of variances of several independent populations belonging to the same location-scale family is proposed. An extensive simulation study within the class of locati...

Score and Wald tests for the homogeneity of inverse Gaussian scale parameters based on computational approach test.

Publication Type: Academic Journal

Source(s): Communications in Statistics: Simulation & Computation. 2022, Vol. 51 Issue 11, p6649-6666. 18p.

Abstract: In this study, we first obtain likelihood based Wald and score tests for testing the homogeneity of scale parameters of k independent inverse Gaussian populations. After that, we adapt these tests into the computational approach test procedure. We also...

Asymptotic analysis of singular likelihood ratio of normal mixture by Bayesian learning theory for testing homogeneity.

Publication Type: Academic Journal

Source(s): Communications in Statistics: Theory & Methods. 2022, Vol. 51 Issue 17, p5873-5888. 16p.

Abstract: When we use the normal mixture model, the optimal number of the components describing the data should be determined. Testing homogeneity is good for this purpose; however, to construct its theory is challenging, since the test statistic does not conver...

On the anomalous homogeneity of hydrogen-disordered ice and its origin.

Publication Type: Academic Journal

Source(s): Journal of Chemical Physics. 10/28/2021, Vol. 155 Issue 16, p1-7. 7p.

Abstract: Pauling's successful estimation of the residual entropy of hydrogen-disordered ice was based on the homogeneity of the binding energy of individual water molecules in ice. However, it has not been explained why the binding energies are homogeneous alth...

Unsupervised Domain Adaptation for Extra Features in the Target Domain Using Optimal Transport.

Publication Type: Academic Journal

Source(s): Neural Computation. Dec2022, Vol. 34 Issue 12, p2432-2466. 35p. 1 Diagram, 4 Charts, 6 Graphs.

Abstract: Domain adaptation aims to transfer knowledge of labeled instances obtained from a source domain to a target domain to fill the gap between the domains. Most domain adaptation methods assume that the source and target domains have the same dimensionalit...

Testing of Homogeneity of Coordinates of Various Permanent GNSS Reference Stations Networks of the Republic of Serbia According to the Common Requirements for Proving Competence.

Publication Type: Academic Journal

Source(s): Sensors (14248220). Oct2022, Vol. 22 Issue 20, pN.PAG-N.PAG. 20p.

Abstract: The validity of the results obtained within different permanent GNSS reference station networks (GNSS Network) must be periodically controlled using criteria that are generally known from statistical analyzes or prescribed by International Standards. P...

New grasshoppers (Orthoptera: Elcanidae, Locustopsidae) from the Lower Cretaceous Crato Formation suggest a biome homogeneity in Central Gondwana.

Publication Type: Academic Journal

Source(s): Historical Biology. Oct2022, Vol. 34 Issue 10, p2070-2078. 9p.

Abstract: †Cratoelcana rasnitsyni sp. nov., new elcanid species, and †Pseudoacrida sennlaubi sp. nov., new locustopsid species, are described from the Lower Cretaceous Crato Formation in Brazil, on the basis of two well-preserved compression fossils. The genus †...

The max‐p‐compact‐regions problem.

Publication Type: Academic Journal

Source(s): Transactions in GIS. Apr2022, Vol. 26 Issue 2, p717-734. 18p.

Abstract: The max‐p‐compact‐regions problem involves the aggregation of a set of small areas into an unknown maximum number (p) of compact, homogeneous, and spatially contiguous regions such that a regional attribute value is higher than a predefined threshold. ...
