| Abstract: | The problem of the best linear unbiased estimate in the general Gauss-Markov model is considered. The relative efficiency of the estimate proposed by Fangxing is generalized and the lower bound of efficiencies of linear unbiased estimate with respect to the general ridge estimate is obtained. |

| Keywords: | least squares estimate generalized ridge estimate relative efficiency lower bound |
