Interpreting Breast Cancer Survival Data by the Hazard Function: Remarkable Findings from Event Dynamics [PDF]

Medicina, 2020
The report addresses the role of the hazard function in the analysis of disease-free survival data in breast cancer. An investigation on local recurrences after mastectomy provided evidence that uninterrupted growth is inconsistent with clinical findings

Hazard function theory for nonstationary natural hazards [PDF]

Natural Hazards and Earth System Sciences, 2016
Impact from natural hazards is a shared global problem that causes tremendous loss of life and property, economic cost, and damage to the environment.

Non-constant Hazard Function and Inflation Dynamics [PDF]

SSRN Electronic Journal, 2011
This paper explores implications of nominal rigidity characterized by a non-constant hazard function for aggregate dynamics. I derive the NKPC under an arbitrary hazard function and parameterize it with the Weibull duration model.

Determining the optimal time to report mortality after lobectomy for lung cancer: An analysis of the time-varying risk of deathCentral MessagePerspective

JTCVS Open, 2023
Objective: Surgical mortality has traditionally been assessed at arbitrary intervals out to 1 year, without an agreed optimum time point. The aim of our study was to investigate the time-varying risk of death after lobectomy to determine the optimum ...

Simulating time-to-event data under the Cox proportional hazards model: assessing the performance of the non-parametric Flexible Hazards Method

Frontiers in Applied Mathematics and Statistics, 2023
Numerous methods and approaches have been developed for generating time-to-event data from the Cox Proportional Hazards (CPH) model; however, they often require specification of a parametric distribution for the baseline hazard even though the CPH model ...

Quantile Regression with a New Exponentiated Odd Log-Logistic Weibull Distribution

Mathematics, 2023
We define a new quantile regression model based on a reparameterized exponentiated odd log-logistic Weibull distribution, and obtain some of its structural properties.

A New Sine Family of Generalized Distributions: Statistical Inference with Applications

Mathematical and Computational Applications, 2023
In this article, we extensively study a family of distributions using the trigonometric function. We add an extra parameter to the sine transformation family and name it the alpha-sine-G family of distributions.

The Asymmetric Laplace Gaussian (ALG) Distribution as the Descriptive Model for the Internal Proactive Inhibition in the Standard Stop Signal Task

Brain Sciences, 2022
Measurements of response inhibition components of reactive inhibition and proactive inhibition within the stop-signal paradigm have been of particular interest to researchers since the 1980s.

Comparison of Multiple Hazard Rate Functions [PDF]

Biometrics, 2015
Summary Many robust tests have been proposed in the literature to compare two hazard rate functions, however, very few of them can be used in cases when there are multiple hazard rate functions to be compared. In this article, we propose an approach for detecting the difference among multiple hazard rate functions.

Statistical Analysis Based on Adaptive Progressive Hybrid Censored Sample From Alpha Power Generalized Exponential Distribution

IEEE Access, 2020
For the alpha power generalized exponential model, the maximum likelihood and Bayes estimations of unknown distribution parameters are discussed under an adaptive Type-II progressive hybrid censored sample.
