摘要：

General rigorous and simplified formulae are reported for the best invariant quadratic unbiased estimates of the variance-covariance components, which can be applied to all least-squares adjustments with the general linear stochastic model. Simplified procedures are given for two cases frequently recurring in geodetic applications: uncorrelated groups of correlated or uncorrelated observations, with more than one variance component in each group.
