Multivariate hazard orderings of discrete random vectors [PDF]

The task of comparing two random vectors with respect to some multivariate stochastic ordering usually involves an infinite number of comparisons. Dyckerhoff and Mosler (1997) proved that, when the random vectors have finite supports, this task, for some

Testing departures from the increasing hazard rate property

, 2023
This paper proposes a nonparametric test to detect violations of the increasing hazard rate property, based on the distance between the empirical distribution function and a shape-constrained estimator. The test is consistent.

Bias in nearest-neighbor hazard estimation [PDF]

In nonparametric curve estimation, the smoothing parameter is critical for performance. In order to estimate the hazard rate, we compare nearest neighbor selectors that minimize the quadratic, the Kullback-Leibler, and the uniform loss.

An Exponentiated Inverse Exponential Distribution Properties and Applications

Axioms
This paper introduces Exponentiated Inverse Exponential Distribution (EIED), a novel probability model developed within the power inverse exponential distribution framework. A distinctive feature of EIED is its highly flexible hazard rate function, which

A rule-of-thumb for the variable bandwidth selection in kernel hazard rate estimation [PDF]

In nonparametric curve estimation the decision about the type of smoothing parameter is critical for the practical performance. The nearest neighbor bandwidth as introduced by Gefeller and Dette 1992 for censored data in survival analysis is specified by

On a New Class of Power-Transformed Bimodal Exponential Distributions with Inferential Procedures and Applications

Mathematical and Computational Applications
In this paper, we introduce a new three-parameter lifetime distribution that is obtained via a power transformation of the modified bimodal exponential model.

Exponentiated (Lehmann Type-II) Nadarajah-Haghighi Distribution: Properties and Applications [PDF]

المجلة العلمية للدراسات والبحوث المالية والتجارية
In this paper we introduce a new distribution called exponentiated (Lehmann type-II) Nadarajah-Haghighi (ENH-II). This version is considered a generalization of the original distribution and is more flexible than it.

The impact of legislation on divorce : a hazard function approach

, 1995
The paper examines the impact of the introduction of no-fault divorce legislation in Australia. The approach used is rather novel, a hazard model of the divorce rate is estimated with the role of legislation captured via a time-varying covariate.

Two Weighted Distributions Generated by Exponential Distribution

Journal of Mathematical Extension, 2015
In this paper, we propose new classes of weighted distributions by incorporating exponential distribution in Azzalini’s method. Resulting weighted models generated by exponential distribution are: the weighted gamma-exponential model and the weighted ...
