Abstract:The least squares estimate and biased estimales (e. g..ordinary ridge estimate. generallied ridge estimate and Stein' shrunken estimate etc.) for variance-covariance components in stochastlcal model are presented by introducing dispersion-mean correspondence and their optimalities are shown.
Keywords:Survey adjustment  Stochastical model  Variance m covariance components  Mean parameter  Least squares estimation  Biased estimation  Mean squares error
