Heteroscedastic controlled calibration model applied to analytical chemistry
(JOHN WILEY & SONS LTD, 2010)
In chemical analyses performed by laboratories, one faces the problem of determining the concentration of a chemical element in a sample. In practice, one deals with the problem using the so-called linear calibration model, ...
Bayesian analysis of the calibration problem under elliptical distributions
(ELSEVIER SCIENCE BV, 2000)
In this paper we discuss calibration problems under dependent and independent elliptical family of distributions. In the dependent case, it is shown that the posterior distribution of the quantity of interest is robust ...
On the skew-normal calibration model
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2010)
In this article, we present the EM-algorithm for performing maximum likelihood estimation of an asymmetric linear calibration model with the assumption of skew-normally distributed error. A simulation study is conducted ...
Statistical analysis of controlled calibration model with replicates
(Taylor & Francis LtdAbingdonInglaterra, 2013)
Bayesian calibration under a student-t model
(SPRINGER HEIDELBERG, 1998)
In this paper we consider linear calibration problems in regressions models with independent errors distributed according to the Student-t distribution. The approach followed is Bayesian, thus, involving the need for the ...
Line based camera calibration in machine vision dynamic applications
(1999-12-01)
The problem of dynamic camera calibration considering moving objects in close range environments using straight lines as references is addressed. A mathematical model for the correspondence of a straight line in the object ...
A calibration function from change points using linear mixed models
(2019-04-08)
The change point problem is an interesting topic in both cross-sectional and longitudinal settings. In the cross-sectional scenario, the change point problem has been studied extensively. In longitudinal settings, authors ...
Local influence in comparative calibration models under elliptical t-distributions
