Abstract:The results of the robust estimates depend mainly on their weight functions. But nearly all weight functions are empirical and their parameters are determined personally. A new approach of determining the weight functions of the robust estimates has been presented and the universal formulae of the robust estimaters of parameter vector and variance components were established according to statistics.
Key words: variance component robust estimate adjustment model
