Construction D-optimal designs of experiments for linear multiple regression with heteroscedastic observations

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
In article the problem of construction exact D-optimal designs of experiments for linear multiple regression in a case when variance of errors of observations depend on a point in which is made is investigated.

Bayesian Exploration of Phenomenological EoS of Neutron/Hybrid Stars with Recent Observations

open access: yesParticles, 2023
The description of the stellar interior of compact stars remains as a big challenge for the nuclear astrophysics community. The consolidated knowledge is restricted to density regions around the saturation of hadronic matter ρ0=2.8×1014gcm−3, regimes ...

Effects of outliers on the identification and estimation of GARCH models [PDF]

open access: yes, 2006
This paper analyses how outliers affect the identification of conditional heteroscedasticity and the estimation of generalized autoregressive conditionally heteroscedastic (GARCH) models.

Regression calibration for Cox regression under heteroscedastic measurement error - Determining risk factors of cardiovascular diseases from error-prone nutritional replication data [PDF]

open access: yes, 2003
For instance nutritional data are often subject to severe measurement error, and an adequate adjustment of the estimators is indispensable to avoid deceptive conclusions.

A new heteroscedastic regression to analyze mass loss of wood in civil construction in Brazil

open access: yes, 2021
A heteroscedastic regression based on the odd log-logistic Marshall–Olkin normal (OLLMON) distribution is defined by extending previous models. Some structural properties of this distribution are presented.

Relative effects of statistical preprocessing and postprocessing on a regional hydrological ensemble prediction system [PDF]

open access: yesHydrology and Earth System Sciences, 2018
The relative roles of statistical weather preprocessing and streamflow postprocessing in hydrological ensemble forecasting at short- to medium-range forecast lead times (day 1–7) are investigated.

Generalized Nonlinear Least Squares Method for the Calibration of Complex Computer Code Using a Gaussian Process Surrogate

open access: yesEntropy, 2020
The approximated nonlinear least squares (ALS) method has been used for the estimation of unknown parameters in the complex computer code which is very time-consuming to execute.
