Reliability and Hazard Rate Estimation for Expo- nential Populations
, 2010 This thesis deals with the estimation of reliability and hazard rate for exponential distribution from a decision theoretic point of view. In Chapter 1, we give a detailed review of the existing literature on the following problems : (i) estimation of ...

Optimal Retirement Age: Death Hazard Rate Approach [PDF]
A model with special attention on the (subjective) survival probability is proposed to understand salient aspects of retirement age decision. Optimal retirement age results are derived with a death hazard rate function having non-negative duration ...

On some length biased inequalities for reliability measures
Journal of Inequalities and Applications, 2000 In this note, inequalities for length biased and the original residual life function and equilibrium distribution function with monotone hazard rate and mean residual life functions are derived.

Molecular Oncology, EarlyView.Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Discrete New Generalized Pareto Distribution
StatisticaIn this paper we propose a discrete analogue of New Generalized Pareto distribution as a new discrete model using general approach of discretization of continuous distribution. The structural properties of the new distribution are discussed.

Molecular Oncology, EarlyView.Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...

Some nonparametric methods in estimating the hazard rate function
, 1989 The hazard rate function h{x) = f{x)/[1-F{x)], corresponding to a distribution function F with density function / , is one of the most important parameters in reliability and other fields, since h{x)dx can be interpreted as the probability that an object

A comparison study between three different Kernel estimators for the Hazard rate function
, 2017 Kernel estimation is one of the most important data analytical tool, if we consider the non parametric approach in the estimation of the probability density function.

Molecular Oncology, EarlyView.Circulating tumor cells (CTCs) and plasma cell‐free DNA (cfDNA) were analyzed to detect ESR1 mutations and methylation in patients with advanced breast cancer. CTC‐derived DNA showed higher sensitivity for mutation detection and revealed complementary genetic and epigenetic alterations, highlighting the added value of CTC analysis for understanding ...
