1. Robustness optimal spring balance weighing designs for estimation total weight Creator: Ceranka, Bronisław and Graczyk, Małgorzata Format: bez média and svazek Type: model:article and TEXT Subject: robustness, spring balance weighing design, and total weight Language: English Description: In this paper we develop the theory of spring balance weighing designs with non-positive correlated errors for that the lower bound of the variance of estimated total weight is attained.
