Parameter inference from event ensembles and the top-quark mass

open access: yesJournal of High Energy Physics, 2021
One of the key tasks of any particle collider is measurement. In practice, this is often done by fitting data to a simulation, which depends on many parameters.

A Statistical Detection of an Anomaly from a Few Noisy Tomographic Projections

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
The problem of detecting an anomaly/target from a very limited number of noisy tomographic projections is addressed from the statistical point of view. The imaged object is composed of an environment, considered as a nuisance parameter, with a possibly ...

Bayesian Classification of Multivariate Autoregressive Sources with Unknown Order. [PDF]

open access: yesThe Egyptian Statistical Journal, 1997
The objective of this paper is to present a Bayesian classification technique that can be used to classify a multivariate time series realization into one of several multivariate autoregressive sources.

THE EFFICIENCY OF EMPIRICAL LIKELIHOOD WITH NUISANCE PARAMETERS [PDF]

open access: yesJournal of Mathematics and Statistics, 2014
In this study we check the asymptotic efficiency of empirical likelihood in the presence of nuisance parameters combined with augmented moment conditions. We show that in the presence of nuisance parameters, the asymptotic efficiency of the empirical likelihood estimator of the parameter of interest will increase by adding more moment conditions, in ...

Bayesian Discrepancy Measure: Higher-Order and Skewed Approximations

open access: yesEntropy
The aim of this paper is to discuss both higher-order asymptotic expansions and skewed approximations for the Bayesian discrepancy measure used in testing precise statistical hypotheses.

Correlated systematic uncertainties and errors-on-errors in measurement combinations with an application to the 7–8 TeV ATLAS–CMS top quark mass combination

open access: yesEuropean Physical Journal C: Particles and Fields
The Gamma Variance Model is a statistical model that incorporates uncertainties in the assignment of systematic errors (informally called errors-on-errors). The model is of particular use in analyses that combine the results of several measurements.

Generalized Inferences about the Mean Vector of Several Multivariate Gaussian Processes

open access: yesJournal of Probability and Statistics, 2015
We consider in this paper the problem of comparing the means of several multivariate Gaussian processes. It is assumed that the means depend linearly on an unknown vector parameter θ and that nuisance parameters appear in the covariance matrices.

On a Comparison of Tests of Homogeneity of Binomial Proportions [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2013
There are multiple tests of homogeneity of binomial proportions in the statistics literature. However, when working with sparse data, most test procedures may fail to perform well.

Comparison between Frequentist Test and Bayesian Test to Variance Normal in the Presence of Nuisance Parameter: One-sided and Two-sided Hypothesis

open access: yesپژوهش‌های ریاضی, 2016
This article is concerned with the comparison P-value and Bayesian measure for the variance of Normal distribution with mean as nuisance paramete. Firstly, the P-value of null hypothesis is compared with the posterior probability when we used a fixed ...
