umvue造句

• For practical statistics problems, it is important to determine the UMVUE if one exists, since less-than-optimal procedures would naturally be avoided, other things being equal.
• Other desirable properties for estimators include : UMVUE estimators that have the lowest variance for all possible values of the parameter to be estimated ( this is usually an easier property to verify than efficiency ) and consistent estimators which converges in probability to the true value of such parameter.
