Design of the Bartlett and Hartley tests for homogeneity of variances under indeterminacy environment

open access: yesJournal of Taibah University for Science, 2020
The existing Bartlett’s test and Hartley’s test under classical statistics can be applied only when all observations in the sample are determined, precise and determinate. In some complex situations, it may not possible to measure the exact observations.

Monitoring of Time and Cost Variances of Schedule Using Simple Earned Value Method Indicators

open access: yesApplied Sciences (Switzerland), 2021
The Planning and implementation of construction projects are difficult processes and are burdened with many risk elements. The budget spread over time, which is developed on the basis of the schedule, presents the expected distribution of costs ...

An increasing number of convolutional neural networks for fracture recognition and classification in orthopaedics: are these externally validated and ready for clinical application?

open access: yesBone & Joint Open, 2021
Aims: The number of convolutional neural networks (CNN) available for fracture detection and classification is rapidly increasing. External validation of a CNN on a temporally separate (separated by time) or geographically separate (separated by location)

Normalised degree variance [PDF]

open access: yesApplied Network Science, 2020
AbstractFinding graph indices which are unbiased to network size and density is of high importance both within a given field and across fields for enhancing comparability of modern network science studies. The degree variance is an important metric for characterising network degree heterogeneity.

$k$-Variance: A Clustered Notion of Variance

open access: yesSIAM Journal on Mathematics of Data Science, 2022
We introduce $k$-variance, a generalization of variance built on the machinery of random bipartite matchings. $K$-variance measures the expected cost of matching two sets of $k$ samples from a distribution to each other, capturing local rather than global information about a measure as $k$ increases; it is easily approximated stochastically using ...

Variation in mutational (co)variances

open access: yesG3: Genes, Genomes, Genetics, 2022
Because of pleiotropy, mutations affect the expression and inheritance of multiple traits and, together with selection, are expected to shape standing genetic covariances between traits and eventual phenotypic divergence between populations.

Le quotient de deux variances corr\'el\'ees, sa distribution et son test [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2016
The joint sampling distribution of two correlated variances, i.e. variances stemming from a bivariate normal distribution or from two normal $\rho $-correlated distributions, is hardly known and used, by contrast with the distribution of $F$, the ...
