✦ Synopsis

The paper deals with the problem of estimating the individual weights of objects under a biased spring balance weighing design with equal correlations of errors in the model. A lower bound for the variance of each of the estimated weights resulting from this biased spring balance neighing design is obtained and a necessary and sufficient condition for this lower bound t o be attained is given. The incidence matrix of il B I B design has been used to construct optimum biased spring balance neighing designs.
