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.

Bayes Estimation of Parameter of Exponential Distribution under a Bounded Loss Function

open access: yes, 2013
The aim of this study is to study the Bayes estimation of parameter of exponential distribution under a bounded loss function, named reflected gamma loss function, which proposed by Towhidi and Behboodian (1999).

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

open access: yesAdvanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Comparison of estimators under different loss functions for two-parameter bathtub - shaped lifetime distribution

open access: yesCumhuriyet Science Journal, 2020
Chen is suggested a two-parameter distribution. This distribution can have increasing failure rate function or a bathtub-shaped that allows it to fit real lifetime data sets.

Continuous‐Flow Photocatalytic Degradation of Glyphosate and Aminomethylphosphonic Acid Under Simulated Sunlight with TiO2‐Coated Poly(vinylidene fluoride) Membrane

open access: yesAdvanced Functional Materials, EarlyView.
Glyphosate (GLY) and its primary metabolite, aminomethylphosphonic acid (AMPA), are photodegraded using a poly(vinylidene fluoride) membrane with immobilized titanium dioxide (PVDF‐TiO2) in a continuous flow‐through operation under solar light. At optimized conditions, the PVDF‐TiO2 membrane achieved 95% GLY and 80% AMPA removal with •O2− as the ...

On Bayes estimates

open access: yesJournal of Multivariate Analysis, 1973
AbstractIn this paper the author tries to give general conditions for the existence of Bayes estimates and for the consistency of sequences of Bayes estimates.In Section 3 we prove existence theorems for Bayes estimates, which contain those of DeGroot and Rao [3], as a special case.

Bayes Estimation with Convex Loss

open access: yesThe Annals of Mathematical Statistics, 1963
Let $X$ be a generalized random variable taking values in an abstract set $\mathscr{X}$ on which is defined an appropriate $\sigma$-field of subsets. Suppose that the distribution of $X$ depends on a real parameter $\Theta$ and that it is desired to estimate the value of $\Theta$ from an observation on $X$.

Consistent nonparametric Bayesian inference for discretely observed scalar diffusions [PDF]

open access: yes, 2013
We study Bayes procedures for the problem of nonparametric drift estimation for one-dimensional, ergodic diffusion models from discrete-time, low-frequency data. We give conditions for posterior consistency and verify these conditions for concrete priors,
