Econometric estimation of proportional hazard models [PDF]

open access: yesJournal of Economics and Business, 1993
When analyzing duration data, covariates are typically assumed to modify hazard rates through the use of the proportional hazard model, in which the baseline hazard is multiplied by some function of the regressors and associated parameters, g(•), to determine individual hazard rates. The specification for g(•) which is in virtually universal use, g(•) =

Personalized Standard Deviations Improve the Baseline Estimation of Collaborative Filtering Recommendation

open access: yesApplied Sciences, 2020
Baseline estimation is a critical component for latent factor-based collaborative filtering (CF) recommendations to obtain baseline predictions by evaluating global deviations for both users and items from personalized ratings.

Estimation of false discovery proportion under general dependence [PDF]

open access: yesBioinformatics, 2006
AbstractMotivation: Wide-scale correlations between genes are commonly observed in gene expression data, due to both biological and technical reasons. These correlations increase the variability of the standard estimate of the false discovery rate (FDR).

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

New Randomized Response Procedures [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2012
This article focuses on the estimation of population proportion when the study variable is sensitive in nature. Two implicit randomized response techniques are proposed where the unrelated trait can be chosen subjectively.

Estimating the proportion of neutral mutants

open access: yesGenetical Research, 1987
SummaryKimura used the heterozygosity and the number of low-frequency alleles to estimate that about 14% of mutations are selectively neutral. The method is shown to be subject to biases and to disruption due to bottleneck effects. Let deleterious alleles have selective disadvantage,s, compared with neutral alleles and letNedenote the effective diploid

Parent‐to‐Child Information Disclosure in Pediatric Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

Sensitive proportion in ranked set sampling.

open access: yesPLoS ONE, 2021
This paper considers the concomitant-based rank set sampling (CRSS) for estimation of the sensitive proportion. It is shown that CRSS procedure provides an unbiased estimator of the population sensitive proportion, and it is always more precise than ...
