Studying a Sort of Special Circumstance of Variance Estimation of Unit Weight

Article Preview

Abstract:

When quantity of superfluous survey equals to zero,and sum of residuals squared with weight equals to zero,variance estimation of unit weight is found that it doesnt only equal to zero,but also equals to any plus real number.Then,a sort of imitative example was put forward to support the new conclusion.So,this paper has perfected variance estimation of unit weight based on theory and application in some aspect, and,has solved that,when quantity of superfluous survey equals to zero,we can still assess accuracy based on number.
