Mortality as a Function of Survival
Demography, 2023 Abstract Everyone has a chronological age. Because survivorship declines relentlessly in populations with age-specific death rates greater than zero, everyone also has a survivorship age (“s-age”), the age at which a proportion s of the population is still alive. S-ages can be estimated for both periods and cohorts. While trajectories of

Learning Survival Distribution with Implicit Survival Function
Proceedings of the Thirty-Second International Joint Conference on Artificial Intelligence, 2023 Survival analysis aims at modeling the relationship between covariates and event occurrence with some untracked (censored) samples. In implementation, existing methods model the survival distribution with strong assumptions or in a discrete time space for likelihood estimation with censorship, which leads to weak generalization.

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

KAPLAN-MEIER AND NELSON-AALEN ESTIMATORS FOR CREDIT SCORING
Media Statistika, 2023 Financial institutions use credit scoring analysis to predict the probability that a customer will default. In this paper, we determine the probability of default using nonparametric survival analysis that are Kaplan-Meier and Nelson-Aalen.
