Comparison of quantile regression and censored quantile regression methods in the case of chicken consumption

open access: yesDesimal, 2023
The censored quantile regression method is a parameter estimation method that can be used to overcome censored data and BLUE (Best Linear Unbiased Estimator) assumptions that are not met.

Random forest for spatial prediction of censored response variables

open access: yesArtificial Intelligence in Geosciences, 2021
The spatial prediction of a continuous response variable when spatially exhaustive predictor variables are available within the region under study has become ubiquitous in many geoscience fields. The response variable is often subject to detection limits

Quantile Regression Approach to Model Censored Data

open access: yesScience and Technology Indonesia, 2020
The censored quantile regression model is derived from the censored model. This method is used to overcome problems in modeling censored data as well as to overcome the assumptions of linear models that are not met.

Wavelet Support Vector Censored Regression

open access: yesAnalytics, 2023
Learning methods in survival analysis have the ability to handle censored observations. The Cox model is a predictive prevalent statistical technique for survival analysis, but its use rests on the strong assumption of hazard proportionality, which can ...

The Compound Gompertz Distribution [PDF]

open access: yesThe Egyptian Statistical Journal, 1995
In this study the properties of the compound Gompertz distribution have been studied. Parameters have been estimated for non-censored, for singly censored and for progressively censored data.

An Approximation for The Censored Values In Linear Regression Models [PDF]

open access: yesThe Egyptian Statistical Journal, 1990
Least squares estimation of the unknown parameters of the linear regression model with censored data from the right has been discussed by many authors.

Sensitivity of censored data analysis to determine the characteristic value of structural timber

open access: yesJournal of Wood Science, 2020
In structural timber tests, unintended failure mechanisms occur frequently in specimens and their results are called censored data. There are two censored data analysis: censored maximum likelihood estimation (CMLE) and Kaplan–Meier (KM) method.

On Bayesian modeling of censored data in JAGS

open access: yesBMC Bioinformatics, 2022
Background Just Another Gibbs Sampling (JAGS) is a convenient tool to draw posterior samples using Markov Chain Monte Carlo for Bayesian modeling. However, the built-in function dinterval() for censored data misspecifies the default computation of ...

Estimating Dynamic Signals From Trial Data With Censored Values

open access: yesComputational Psychiatry, 2017
Censored data occur commonly in trial-structured behavioral experiments and many other forms of longitudinal data. They can lead to severe bias and reduction of statistical power in subsequent analyses.

Regression models for interval censored data using parametric pseudo-observations

open access: yesBMC Medical Research Methodology, 2021
Background Time-to-event data that is subject to interval censoring is common in the practice of medical research and versatile statistical methods for estimating associations in such settings have been limited.
