Testing Exponentiality Based on Rényi Entropy With Progressively Type-II Censored Data
Renyi Entropy hazard function Monte Carlo simulation order statistics Type-II progressively censored data
2013/4/28
We express the joint R\'enyi entropy of progressively censored order statistics in terms of an incomplete integral of the hazard function, and provide a simple estimate of the joint R\'enyi entropy of...
Using Moving Average Method To Estimate Entropy In Testing Exponentiality For Type-II Censored Data
Entropy Monte Carlo simulation Kullback-Leibler distance mov-ing average method Hazard function.
2012/9/19
In this paper, we introduce a modified test statistic, by applying moving average method and present a new cdf estimator to estimate the joint entropy of the type-II censored data. We also establish a...
Improved EM for Mixture Proportions with Applications to Nonparametric ML Estimation for Censored Data
AECM cocktail algorithm data augmentation doubly censored data EM globalconvergence NPMLE nonparametric mixtures
2010/3/10
Improved EM strategies, based on the idea of efficient data augmentation (Meng and van
Dyk 1997, 1998), are presented for ML estimation of mixture proportions. The resulting
algorithms inherit the s...
Uniform limit laws of the logarithm for estimators of the additive regression function in the presence of right censored data
nonparametric estimation additive regression function censored data uniform laws of the logarithm
2009/9/16
It has been recently shown that nonparametric estimators of the additive regression function could be obtained in the presence of right censoring by coupling the marginal integration method with initi...
On lasso for censored data
Accelerated failure time model Buckley-James estimator least angle regression survival analysis synthetic data
2009/9/16
In this paper, we propose a new lasso-type estimator for censored data after one-step imputatation. While several penalized likelihood estimators have been proposed for censored data variable selectio...
ESTIMATIONS OF THE PARAMETERS OF THE WEIBULL DISTRIBUTION WITH PROGRESSIVELY CENSORED DATA
Confidence interval Joint confidence region Maximum likelihood estimator Progressively type-II censored sample
2009/3/11
We obtained estimation results concerning a progressively type-II censored sample from a two-parameter Weibull distribution. The maximum likelihood method is used to derive the point estimators of the...
Influence diagnostics in exponentiated-Weibull regression models with censored data
Exponentiated-Weibull distribution censored data local influence influence diagnostic survival data
2009/2/23
Diagnostic methods have been an important tool in regression analysis to detect anomalies, such
as departures from the error assumptions and the presence of outliers and influential observations with...
Uniform limit laws of the logarithm for estimators of the additive regression function in the presence of right censored data
nonparametric estimation additive regressionfunction right censored data uniform laws of the logarithm
2010/4/26
It has been recently shown that nonparametric estimators of
the additive regression function could be obtained in the presence of right
censoring by coupling the marginal integration method with ini...
Active Set and EM Algorithms for Log-Concave Densities Based on Complete and Censored Data
Active Set EM Algorithms Log-Concave Densities Complete and Censored Data
2010/4/30
We develop an active set algorithm for the maximum likelihood estimation of a
log–concave density based on complete data. Building on this fast algorithm, we introduce an EM algorithm to treat arbitr...
Density Estimation of Censored Data with Infinite-Order Kernels
Density estimation hazard function estimation infinite-order kernels nonparametric estimation
2010/4/28
Higher-order accurate density estimation under random right censorship is achieved
using kernel estimators from a family of infinite-order kernels. A compatible bandwidth
selection procedure is also...
