Computing the exact distribution of the Bartlett's test statistic by numerical inversion of its characteristic function [PDF]

open access: yesJournal of Applied Statistics, 2020
Application of the exact statistical inference frequently leads to non-standard probability distributions of the considered estimators or test statistics.

Linguistic Inversion and Numerical Estimation [PDF]

open access: yesJournal of Numerical Cognition, 2020
Number line estimation (NLE) performance is usually believed to depend on the magnitudes of presented numerals, rather than on the particular digits instantiating those magnitudes.

Estimating photosynthetic traits from reflectance spectra: A synthesis of spectral indices, numerical inversion, and partial least square regression. [PDF]

open access: yesPlant Cell Environ, 2020
The lack of efficient means to accurately infer photosynthetic traits constrains understanding global land carbon fluxes and improving photosynthetic pathways to increase crop yield. Here, we investigated whether a hyperspectral imaging camera mounted on

Distribution functions of magnetic nanoparticles determined by a numerical inversion method

open access: yesNew Journal of Physics, 2017
In the present study, we applied a regularized inversion method to extract the particle size, magnetic moment and relaxation-time distribution of magnetic nanoparticles from small-angle x-ray scattering (SAXS), DC magnetization (DCM) and AC ...

A Rapid Numerical Algorithm to Compute Matrix Inversion [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
The aim of the present work is to suggest and establish a numerical algorithm based on matrix multiplications for computing approximate inverses. It is shown theoretically that the scheme possesses seventh-order convergence, and thus it rapidly converges.

Language influences on numerical development – Inversion effects on multi-digit number processing

open access: yesFrontiers in Psychology, 2013
In early numerical development, children have to become familiar with the Arabic number system and its place-value structure. The present review summarizes and discusses evidence for language influences on the acquisition of the highly transparent ...

A Review on the Numerical Inversion Methods of Relative Permeability Curves

open access: yesProcedia Engineering, 2012
In general, relative permeability data can be obtained from laboratory coreflooding experiments. Such experimental data can be interpreted analytically or numerically.
