Inferences for the Change-Point of The Exponentiated Weibull Hazard Function
Revstat Statistical Journal, 2012 In many applications of lifetime data analysis, it is important to perform inferences about the change-point of the hazard function. The change-point could be a maximum for unimodal hazard functions or a minimum for bathtub forms of hazard functions and

Various Characterizations of Modified Weibull and Log Modified Distributions [PDF]
, 2012 Various characterizations of the well-known modifiedWeibull and log-modifiedWeibull distributions are presented. These characterizations are based on a simple relationship between two truncated moments; on the hazard function and on functions of the ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Detecting Clinical Risk Shift Through log–logistic Hazard Change-Point Model
MathematicsThe change–point problem is about identifying when a pattern or trend shifts in time–ordered data. In survival analysis, change–point detection focuses on identifying alterations in the distribution of time–to–event data, which may be subject to ...

The Use of Hazard Models for the Analysis of Income Inequalities in Poland
Folia Oeconomica Stetinensia, 2018 The aim of the paper is to examine the income inequalities of men and women in Poland. We estimate conditional cumulative distribution functions for incomes in both groups of people using a flexible hazard-function based estimator in the presence of ...

Nonparametric estimation of a convex bathtub-shaped hazard function
, 2010 In this paper, we study the nonparametric maximum likelihood estimator (MLE) of a convex hazard function. We show that the MLE is consistent and converges at a local rate of $n^{2/5}$ at points $x_0$ where the true hazard function is positive and ...
