Stress-Strength Analysis of Inverse Weibull Model Using Type-II Progressive Hybrid Censoring and Its Application to Light-Emitting Diodes [PDF]
Maǧallaẗ Al-Buḥūṯ Al-TiǧāriyyaẗIn this paper, we discuss the estimation of δ = P(Y < X) based on Type-II progressivehybrid censored samples when X and Y are two independent Inverse Weibull distributionswith different scale parameters, but having the same shape parameter.

Empirical Bayes Reliability Estimation without First Approximating the Proior [PDF]
The Egyptian Statistical Journal, 1980 An estimate of the reliability function is obtained with the underlying exponential life model. The empirical Bayes approach used here, assumes a square error loss and no knowledge of the prior distribution except that it belongs to a class of ...

Advancing Age Modulates Associations Between Cognitive Impairment and Brain Volumes in Early MS
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Introduction Cognitive impairment is common in multiple sclerosis (MS), but manifestations following the first demyelinating event are relatively unexplored. We investigated cross‐sectional associations between magnetic resonance imaging (MRI)–derived brain volumes and the presence of cognitive impairment outcomes five years after the first ...

Bayes Estimates for the Linear Model
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1972 Summary The usual linear statistical model is reanalyzed using Bayesian methods and the concept of exchangeability. The general method is illustrated by applications to two-factor experimental designs and multiple regression.

Frequentist standard errors of Bayes estimators [PDF]
Computational Statistics, 2017 Frequentist standard errors are a measure of uncertainty of an estimator, and the basis for statistical inferences. Frequestist standard errors can also be derived for Bayes estimators. However, except in special cases, the computation of the standard error of Bayesian estimators requires bootstrapping, which in combination with Markov chain Monte ...

Estimation of Multiple Logistic Model by Using Empirical Bayes Weights and Comparing it with the Classical Method with Application [PDF]
المجلة العراقية للعلوم الاحصائية, 2011 In this research, a solution of heteroscedastisity of the random error variance is found in the Multiple Logistic Model when the response variable (dependent) variable is Qualitative by using the method of weighted least squares (WLS) to estimate the ...

An empirical Bayes estimation problem [PDF]
Proceedings of the National Academy of Sciences, 1980 Let x be a random variable such that, given θ, x is Poisson with mean θ, while θ has an unknown prior distribution G . In many statistical problems one wants to estimate as accurately as possible the parameter
