TRANSFORMED DIFFEOMORPHIC KERNEL ESTIMATION OF HAZARD RATE FUNCTION [PDF]

open access: yesDemonstratio Mathematica, 2001
Summary: A transformed diffeomorphic kernel estimator of the hazard rate function in the presence of censoring is constructed. The estimator is defined in the framework of a multiplicative intensity point process model. It is shown that the proposed estimator is asymptotically unbiased, consistent and asymptotically normal. Analysis in the reduction of

Some new results on bathtub-shaped hazard rate models

open access: yesMathematical Biosciences and Engineering, 2022
The most common non-monotonic hazard rate situations in life sciences and engineering involves bathtub shapes. This paper focuses on the quantile residual life function in the class of lifetime distributions that have bathtub-shaped hazard rate functions.

Hazard rate function estimation using Erlang kernel [PDF]

open access: yesPure Mathematical Sciences, 2014
In this paper, we de ne the Erlang kernel and use it to nonparametically estimation of the probability density function (pdf) and the hazard rate function for inde- pendent and identically distributed (iid) data.The bias, variance and the optimal bandwidth of the proposed estimator are investigated.

Hazard Rate Estimation Using Varying Kernel Function for Censored Data Type I

open access: yesمجلة بغداد للعلوم, 2019
In this research, several estimators concerning the estimation are introduced. These estimators are closely related to the hazard function by using one of the nonparametric methods namely the kernel function for censored data type with varying bandwidth ...

Maximum likelihood estimation of a log-concave density and its distribution function: Basic properties and uniform consistency [PDF]

open access: yes, 2009
We study nonparametric maximum likelihood estimation of a log-concave probability density and its distribution and hazard function. Some general properties of these estimators are derived from two characterizations.

A Modification of the Gompertz Distribution Based on the Class of Extended-Weibull Distributions

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
This paper introduces a new four-parameter extension of the generalized Gompertz distributions. This distribution involves some well-known distributions such as extension of generalized exponential, generalized exponential, and generalized Gompertz ...

On Extended Quadratic Hazard Rate Distribution: Development, Properties, Characterizations and Applications [PDF]

open access: yes, 2018
In this paper, we propose a flexible extended quadratic hazard rate (EQHR) distribution with increasing, decreasing, bathtub and upside-down bathtub hazard rate function. The EQHR density is arc, right-skewed and symmetrical shaped.

New One-Parameter Over-Dispersed Discrete Distribution and Its Application to the Nonnegative Integer-Valued Autoregressive Model of Order One

open access: yesMathematics, 2023
Count data arise in inference, modeling, prediction, anomaly detection, monitoring, resource allocation, evaluation, and performance measurement. This paper focuses on a one-parameter discrete distribution obtained by compounding the Poisson and new X ...

About adaptive coding on countable alphabets [PDF]

open access: yes, 2014
This paper sheds light on universal coding with respect to classes of memoryless sources over a countable alphabet defined by an envelope function with finite and non-decreasing hazard rate. We prove that the auto-censuring AC code introduced by Bontemps

A case study of aging intensity function on censored data

open access: yesAlexandria Engineering Journal, 2018
A major concern for applied statisticians is the analysis of survival experiments under censoring. Here we study the aging intensity function and the hazard rate function on a case study of bone marrow transplant in acute leukemia patients, based on ...
