On the Robustness of the Bayes and Wiener Estimators under Model Uncertainty

open access: yes, 2017
This paper deals with the robust estimation problem of a signal given noisy observations. We assume that the actual statistics of the signal and observations belong to a ball about the nominal statistics. This ball is formed by placing a bound on the Tau-

Bayes Double Sample Estimation Procedures

open access: yesThe Annals of Statistics, 1984
Let \(X=(X_ 1,...,X_ d)\) be a random vector with distribution \(dP_{\theta}(x)=\exp(x\cdot \theta -M(\theta))d\mu(x)\). Given the conjugate prior distribution of \(\theta\) and a loss function depending both on an error of estimation and on the cost of sampling, the Bayesian two-stage estimate of \(EX_ 1\) is constructed.

Advancing Age Modulates Associations Between Cognitive Impairment and Brain Volumes in Early MS

open access: yesAnnals 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 Estimators of the Cointegration Space [PDF]

open access: yes, 2003
A neglected aspect of the otherwise fairly well developed Bayesian analysis of cointegration is the point estimation of the cointegration space. It is pointed out here that, due to the well known non-identification of the cointegration vectors, the ...

What is the value of an observable between pre- and postselection?

open access: yes, 2003
Hall's recent derivation of an exact uncertainty relation [Phys. Rev. A64, 052103 (2001)] is revisited. It is found that the Bayes estimator of an observable between pre- and postselection equals the real part of the weak value.

Risk of Non‐Arteritic Anterior Ischemic Optic Neuropathy in Idiopathic Intracranial Hypertension Patients Treated with GLP‐1 Receptor Agonists

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) have demonstrated significant weight‐reducing effects and may offer benefits in idiopathic intracranial hypertension (IIH); however, recent concerns about the risk of non‐arteritic anterior ischemic optic neuropathy (NAION) have emerged.

Classic and Bayes Shrinkage Estimation in Rayleigh Distribution Using a Point Guess Based on Censored Data

open access: yesپژوهش‌های ریاضی, 2018
Introduction      In classical methods of statistics, the parameter of interest is estimated based on a random sample using natural estimators such as maximum likelihood or unbiased estimators (sample information).

Bayesian Estimation of the Exponential Parameter under a Multiply Type-II Censoring Scheme

open access: yesAustrian Journal of Statistics, 2016
This paper provides the estimation of the scale parameter of the exponential distribution under multiply type-II censoring. Using generalized non-informative prior and natural conjugate prior, Bayes estimator and approximate Bayes estimators of the scale

Quasi-Bayesian analysis of nonparametric instrumental variables models

open access: yes, 2013
This paper aims at developing a quasi-Bayesian analysis of the nonparametric instrumental variables model, with a focus on the asymptotic properties of quasi-posterior distributions.

Anti‐CD19 CAR T Cells in Autoimmune Encephalitis: Inflammation Controlled, Neurodegeneration Unchecked?

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Just recently, successful chimeric antigen receptor (CAR) T cell therapy was reported in the first patient with refractory, anti‐diacylglycerol lipase alpha (DAGLA) antibody‐mediated autoimmune encephalitis, achieving partial clinical remission.
