Solving Non-Linear Estimation Equations

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1993
SUMMARY In this paper we consider the numerical computation of a vector parameter estimate θ^ which is a root of a system of unbiased non-linear estimation equations. A sequence {θ  (r)} is constructed which converges with a probability approaching 1 to θ^ from any starting value θ  (0).

Body composition in Nepalese children using isotope dilution: the production of ethnic-specific calibration equations and an exploration of methodological issues. [PDF]

, 2015
Background. Body composition is important as a marker of both current and future health. Bioelectrical impedance (BIA) is a simple and accurate method for estimating body composition, but requires population-specific calibration equations. Objectives. (1)
