Calibration Weighting and Estimation

2020
One of the important features of survey data is the availability of auxiliary information from the survey population. Auxiliary population information may be available from census enumerations or administrative records. It could also be obtained from unusual sources such as satellite images for natural resource inventory surveys or a previous survey ...

Asymptotic minimax calibration estimates

Chemometrics and Intelligent Laboratory Systems, 1996
Abstract This paper gives methods that use measurements from calibrated instruments in an effective and understandable manner. While some chemometric methods such as partial least squares might be considered, the procedures that we use are more transparent. In this paper two simple methods are proposed that use standard and saddlepoint approximations

The Generic Bilinear Calibration-Estimation Problem

International Journal of Computer Vision, 1997
We identify a very general, recurring pattern in a number of well known problems in biological and machine vision. Many problems are of a peculiar double-sided nature: One attempts to estimate certain properties of the environment using a certain type of equipment and simultaneously one attempts to calibrate the same equipment on the structure of the ...

Estimation of the GSSM calibration error

Applied Optics, 2016
The calibration of the tertiary mirror of the Thirty Meter Telescope, also known as the giant science steering mirror (GSSM), is a step of great significance during its testing process. Systematic, drift, and random errors constitute the major limitations to the accuracy of the calibration measurements.

Bayesian calibration for forensic age estimation

Statistics in Medicine, 2015
Forensic medicine is increasingly called upon to assess the age of individuals. Forensic age estimation is mostly required in relation to illegal immigration and identification of bodies or skeletal remains. A variety of age estimation methods are based on dental samples and use of regression models, where the age of an individual is predicted by ...

Calibration for Randomized Response Estimators

Communications in Statistics - Theory and Methods, 2010
In the present article, we consider the calibration procedure for the Warner's and Mangat–Singh's (:M–S) randomized response survey estimators using auxiliary information associated with the variable of interest. In the calibration procedure, we can use auxiliary information such as age, gender, and income for the respondents of RR questions from an ...

CALIBRATION ESTIMATOR

2010
Regresyon tahmin yöntemine benzeyen bir diğer tahmin yöntemi de ayarlama tahmin edicisi yöntemidir. Ayarlama tahmin edicisi yardımcı değişken(ler) bilgisini tahminlerin etkinliğini arttırmak için kullanır. Ayarlama tahmin edicisi, bir veya birden çok yardımcı değişken (x değişkenleri) için yığın toplamlarını bilmeyi gerektirir.

Calibration Estimators in Survey Sampling

Journal of the American Statistical Association, 1992
Abstract This article investigates estimation of finite population totals in the presence of univariate or multivariate auxiliary information. Estimation is equivalent to attaching weights to the survey data. We focus attention on the several weighting systems that can be associated with a given amount of auxiliary information and derive a weighting ...

Camera response estimation. Radiometric calibration

2009 IEEE 5th International Conference on Intelligent Computer Communication and Processing, 2009
Real time vision requires accurate information about the environment that is to be processed. The quality of the acquired images depends on many factors, such as weather and lighting conditions (sun, rain, snow, fog, mist), entering and going out of tunnels, shadows, cars headlights.
