Application of the Biased Spring Balance Weighing Design Theory to Estimation of Differences of Line Effects for Legume Content

Biometrical Journal, 1989
AbstractThe incidence matrix of a BIB design for v treatments has been used to construct a biased spring balance weighing design. Conditions under which an optimum biased spring balance weighing design exists are given. It is also shown how this theory may be utilized to obtain treatment and experiment designs to estimate differences in legume content ...

Relations between Spring and Chemical Balance Weighing Designs with the Diagonal Covariance Matrix of Errors

1995
The paper deals with the problem of estimating the individual weights of objects with minimum variances by using a weighing design with the diagonal covariance matrix of errors in the model. The necessary and sufficient conditions for optimum biased spring balance weighing designs with the diagonal covariance matrix of errors and for optimum chemical ...

Advances in Chemical and Spring Balance Weighing Designs: A systematic review

This paper deals with the review of the literature on Chemical and Spring Balance Weighing Designs. The Weighing problems were initially originated by Yates and after that Hotelling, who led to a precise formulation of the Weighing problem. Eventually, with the passage of time, this problem expanded to form a branch of Design of Experiment.

ON THE ESTIMATION OF TOTAL WEIGHT IN SINGULAR SPRING BALANCE WEIGHING DESIGNS UNDER THE CO VARIANCE MATRIX OF ERRORS s²G

Australian Journal of Statistics, 1989
SummaryThe problem of the estimation of the linear combination of weights, c′w, in a singular spring balance weighing design when the error structure takes the form E(ee′) =s̀2G has been studied. A lower bound for the variance of the estimated linear combination of weights is obtained and a necessary and sufficient condition for this lower bound to be ...
