This paper introduces a new class of estimates for estimating the parameters of a vector autoregressive time series. The estimates minimize a sum of weighted pairwise Euclidean distances and extend the univariate GR-estimates of Terpstra et al. (Statist. Probab. Lett. 51 (2001) 165; Statist. Inferen
