A new distribution-free approach to constructing the confidence region for multiple parameters. [PDF]

open access: yesPLoS ONE, 2013
Construction of confidence intervals or regions is an important part of statistical inference. The usual approach to constructing a confidence interval for a single parameter or confidence region for two or more parameters requires that the distribution ...

Hybrid Segmentation Method With Confidence Region Detection for Tumor Identification

open access: yesIEEE Access, 2021
Segmentation methods can mutually exclude the location of the tumor. However, the challenge of complex location or incomplete identification is located in segmentation challenge dataset.

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.

Confidence Region Identification and Contour Detection in MRI Image. [PDF]

open access: yesComput Intell Neurosci, 2022
Tumour region extraction (RE) method identifies the area of interest in MR imaging as it also highlights tumour boundaries. Some other intensities are existing, they are not visible but have their existence in region, and this region is called growing ...

A Confidence Region Approach to Tuning for Variable Selection. [PDF]

open access: yesJ Comput Graph Stat, 2012
We develop an approach to tuning of penalized regression variable selection methods by calculating the sparsest estimator contained in a confidence region of a specified level.

Joint confidence region estimation of L-moment ratios with an extension to right censored data. [PDF]

open access: yesJ Appl Stat, 2013
L-moments, defined as specific linear combinations of expectations of order statistics, have been advocated by Hosking 7 and others in the literature as meaningful replacements to that of classic moments in a wide variety of applications.

Confidence Intervals and Regions for Proportions under Various Three-Endmember Linear Mixture Models

open access: yesRemote Sensing, 2023
Many studies in recent years have been devoted to estimating the per-pixel proportions of three broad classes of materials (e.g., photosynthetic vegetation, non-photosynthetic vegetation and bare soil) using data from multispectral sensors.

Inference for the Linear IV Model Ridge Estimator Using Training and Test Samples

open access: yesStats, 2021
The asymptotic distribution is presented for the linear instrumental variables model estimated with a ridge penalty and a prior where the tuning parameter is selected with a holdout sample. The structural parameters and the tuning parameter are estimated
