Confidence Region for Calibration Function Coefficients

open access: yesMeasurement Science Review, 2018
The paper deals with the comparative calibration model, i.e. with a situation when both variables are subject to errors. The calibration function is supposed to be a polynomial.

A frequentist analysis of solar neutrino data [PDF]

open access: yes, 2000
We calculate with Monte Carlo the goodness of fit and the confidence level of the standard allowed regions for the neutrino oscillation parameters obtained from the fit of solar neutrino data.

Uncertainty inherent in empirical fitting of distributions to experimental data

open access: yesInternational Journal of Metrology and Quality Engineering, 2013
Treatment of experimental data often entails fitting frequency functions, in order to draw inferences on the population underlying the sample at hand, and/or identify plausible mechanistic models.

On the integrity of deformation monitoring

open access: yesGeomatics, Natural Hazards & Risk, 2020
In safety-critical applications, deformation monitoring systems are required to issue timely alerts when a deformation beyond a critical threshold occurs. Only a very small probability of failing to issue an alert when in fact one should have been given,

Confidence regions in Cox proportional hazards model with measurement errors and unbounded parameter set

open access: yesModern Stochastics: Theory and Applications, 2018
Cox proportional hazards model with measurement errors is considered. In Kukush and Chernova (2017), we elaborated a simultaneous estimator of the baseline hazard rate $\lambda (\cdot )$ and the regression parameter β, with the unbounded parameter set ...

To assess the confidence levels of psychiatrists in physical healthcare competencies in one irish region, and to explore whether confidence was related to learning opportunities

open access: yesEuropean Psychiatry, 2021
Introduction The bi-directional relationship between mental and physical illness is well established. Therefore, in order to lower the already high mortality rates associated with psychiatric disorders, physical health issues must be closely monitored ...

Teetool -- a probabilistic trajectory analysis tool

open access: yesJournal of Open Research Software, 2017
Teetool is a Python package which models and visualises motion patterns found in two- and three-dimensional trajectory data. It models the trajectories as a Gaussian process and uses the mean and covariance of the trajectory data to produce a confidence ...

ROBUST LOW-ALTITUDE IMAGE MATCHING BASED ON LOCAL REGION CONSTRAINT AND FEATURE SIMILARITY CONFIDENCE [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Improving the matching reliability of low-altitude images is one of the most challenging issues in recent years, particularly for images with large viewpoint variation.

Statistical Hypothesis Testing for Asymmetric Tolerance Index

open access: yesApplied Sciences, 2021
Many of the nominal-the-best quality characteristics of important machine tool components, such as inner or outer diameters, have asymmetric tolerances. An asymmetric tolerance index is a function for the average of the process and the standard deviation.

Confidence Intervals and Upper Bounds for Small Signals in the Presence of Background Noise [PDF]

open access: yes, 2000
We discuss a new method for setting limits on small signals in the presence of background noise. The method is based on a combination of a two dimensional confidence region and the large sample approximation to the likelihood ratio test statistic.
