A superior extension for the Lomax distribution with application to Covid-19 infections real data [PDF]
Alexandria Engineering Journal, 2022 We present a new continuous lifetime model with four parameters by combining the Lomax and the Weibull distributions. The extended odd Weibull Lomax (EOWL) distribution is what we’ll call it.

A generalized Gompertz promotion time cure model and its fitness to cancer data [PDF]
HeliyonThe cure models based on standard distributions like exponential, Weibull, lognormal, Gompertz, gamma, are often used to analyze survival data from cancer clinical trials with long-term survivors.

Open Mathematics, 2022 In this article, we propose a Gompertz-two-parameter-Lindley distribution by mixing the frailty parameter of the Gompertz distribution with a two-parameter Lindley distribution. The structural properties of the model, such as shape properties, cumulative

Estimation and inference in adaptive learning models with slowly decreasing gains
Journal of Time Series Analysis, Volume 43, Issue 5, Page 720-749, September 2022., 2022 An asymptotic theory for estimation and inference in adaptive learning models with strong mixing regressors and martingale difference innovations is developed. The maintained polynomial gain specification provides a unified framework which permits slow convergence of agents' beliefs and contains recursive least squares as a prominent special case ...

On the three-spliced Exponential-Lognormal-Pareto distribution
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022 To model statistical data coming from two di erent distributions, Cooray and Ananda [1] introduced a composite (two-spliced) Lognormal-Pareto model, that was further extended by Scollnik [9] and fitted to insurance data.

Infinite secret sharing – Examples
Journal of Mathematical Cryptology, 2014 The motivation for extending secret sharing schemes to cases when either the set of players is infinite or the domain from which the secret and/or the shares are drawn is infinite or both, is similar to the case when switching to abstract probability ...

Volatility filtering in estimation of kurtosis (and variance)
Dependence Modeling, 2019 The kurtosis of the distribution of financial returns characterized by high volatility persistence and thick tails is notoriously difficult to estimate precisely.
