Estimation of Nonlinear Errors-in-Variables Models

Abstract

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. In deriving the results it is assumed that the covariance matrix of the observational errors is known and that this covariance matrix is $o(n^{-1/3})$, where $n$ is the index of the sequence of estimators.
