A likelihood framework for deterministic hydrological models and the importance of non-stationary autocorrelation [PDF]

open access: yesHydrology and Earth System Sciences, 2019
The widespread application of deterministic hydrological models in research and practice calls for suitable methods to describe their uncertainty. The errors of those models are often heteroscedastic, non-Gaussian and correlated due to the memory ...

Errors-in-Variables Models [PDF]

open access: yes, 2000
Errors-in-variables (EIV) models axe regression models in which the regres-sors axe observed with errors. These models include the linear EIV models, the nonlinear EIV models, and the partially linear EIV models. Suppose that we want to investigate the relationship between the yield (Y) of corn and available nitrogen (X) in the soil.

Estimation of Nonlinear Errors-in-Variables Models

open access: yesThe Annals of Statistics, 1982
An estimation procedure is presented for the coefficients of the nonlinear functional relation, where observations are subject to measurement error. The distributional properties of the estimators are derived, and a consistent estimator of the covariance matrix is given.

The large deviation for the least squares estimator of nonlinear regression model based on WOD errors

open access: yesJournal of Inequalities and Applications, 2016
As a kind of dependent random variables, the widely orthant dependent random variables, or WOD for short, have a very important place in dependence structures for the intricate properties.
