Study of a Fractal-Fractional Smoking Models with Relapse and Harmonic Mean Type Incidence Rate

open access: yesJournal of Function Spaces, 2021
This manuscript investigates fractal-fractional order smoking models with relapse and harmonic mean type incidence rate under the Caputo derivative. We derive the existence and unique results about the solution for the considered model via fixed point ...

Stochastic Order and Generalized Weighted Mean Invariance

open access: yesEntropy, 2021
In this paper, we present order invariance theoretical results for weighted quasi-arithmetic means of a monotonic series of numbers. The quasi-arithmetic mean, or Kolmogorov–Nagumo mean, generalizes the classical mean and appears in many disciplines ...

Digital image contrast assessment based on the Weibull distribution parameters

open access: yesСистемный анализ и прикладная информатика, 2021
The goal of the studies described in the paper is to find a quantitative assessment that maximally correlates with the subjective assessment of the contrast image quality in the absence of reference image.

The harmonic mean χ2‐test to substantiate scientific findings [PDF]

open access: yesJournal of the Royal Statistical Society: Series C (Applied Statistics), 2019
Statistical methodology plays a crucial role in drug regulation. Decisions by the US Food and Drug Administration or European Medicines Agency are typically made based on multiple primary studies testing the same medical product, where the two‐trials ...
