ABSTRACT Cardiometabolic dysfunction in patients with type 2 diabetes (T2D) is reflected by multiple risk factors and cannot be fully characterized by any single biomarker. Item response theory (IRT) provides a framework for integrating observed risk factors into latent measures of underlying cardiometabolic dysfunction.

Abstract Passive microwave radiances near 23.8 GHz constrain lower‐tropospheric water vapor, but this protected window lies adjacent to fifth‐generation (5G) telecommunications spectrum. We quantify how projected terrestrial 5G leakage propagates through county‐scale deployment projections, directional antenna geometry, synthetic contamination of AMSU ...

On weighted exponential-Gompertz distribution: properties and application
In this paper, we introduce a new distribution generated by an integral transform of the probability density function of the weighted exponential distribution. This distribution is called the weighted exponential-Gompertz (WE-G). Its hazard rate function

On Gamma-Gompertz-Makeham Assurances and Life Annuities
We focus on the gamma-Gompertz-Makeham model, and derive useful structural properties for this mortality model. We provide the basic properties like moments, remaining life expectancy, single life annuity, among many others, in closed form, and so it ...

The Burr XII–Gompertz Distribution: A Competing Risks Model With Applications to Lifetime Data
In this article, we introduce a novel four-parameter lifetime distribution that is constructed by compounding the Burr XII and Gompertz models in a sequential system and is known as the Burr XII–Gompertz distribution.

Objective Posterior Analysis of kth Record Statistics in Gompertz Model
The Gompertz distribution has proven highly valuable in modeling human mortality rates and assessing the impacts of catastrophic events, such as plagues, financial crashes, and famines.

Characterizations and Kullback-Leibler Divergence of Gompertz Distributions
In this note, we characterize the Gompertz distribution in terms of extreme value distributions and point out that it implicitly models the interplay of two antagonistic growth processes. In addition, we derive a closed form expressions for the Kullback-Leibler divergence between two Gompertz Distributions. Although the latter is rather easy to obtain,

The Gompertz distribution and its applications.
"In this paper we study the underlying Gompertz distribution and develop formulae for the moments and other characteristics of this useful but apparently unknown distribution. We find that the skewness and kurtosis of the distribution are fixed constants independent of the two distribution parameters, and this would appear to be the reason for the ...
