| Abstract: | In this paper we take the normal distribution of cutting off tails as the error model of surveying adjustment,so as to dcduee maximum likelihood estimation to submit the normal dis-tribution of cutting off tails.Besides,relationships between scveral sound Robust estimation asethods appeared in literture of surveying and the normal distribution of cutting off tails are discussed.Furthermore,some existing problems of these Robust estimation methods in the practical application are probed into. |
