TAUS: Target‐Age Unified Survival. Survival Analysis Without Assuming Proportional Hazards or Parameterising the Survival Function [PDF]
Ecology and EvolutionStandard survival analyses often assume proportional hazards (PH) or impose parametric survival functions that poorly represent real populations. Ecological applications are further limited by missing age data.

Neutrosophic Generalized Rayleigh Distribution with Application [PDF]
Neutrosophic Sets and Systems, 2023 In this paper, we consider the neutrosophic generalized Rayleigh distribution (NGRD). Various neutrosophic properties of NGRD are developed and discussed. The developed distribution is specifically more useful to model indeterminate data which are skewed

Risks, 2021 In the presence of reinsurance, an insurer may effectively reduce its (aggregated) loss by partially ceding such a loss to a reinsurer. Stop-loss and quota-share reinsurance contracts are commonly agreed between these two parties.

On the Generalized Odd Transmuted Two-Sided Class of Distributions
Statistica, 2021 In this paper, a general class of two-sided lifetime distributions is introduced via odd ratio function, the well-known concept in survival analysis and reliability engineering.

Entropy, 2023 We present the truncated Lindley-G (TLG) model, a novel class of probability distributions with an additional shape parameter, by composing a unit distribution called the truncated Lindley distribution with a parent distribution function G(x).

A New Lifetime Distribution with Decreasing and Upside-Down Bathtub-Shaped Hazard Rate Function
Statistica, 2020 We introduce a new lifetime distribution, called the alpha-power transformed Lomax (APTL) distribution which generalizes the Lomax distribution to provide better fits than the Lomax distribution and some of its known generalizations.
