admissible estimate

基本解释

A necessary and sufficient condition of a class of non-homogeneous quadratic estimate admissible was given .
并得到了一类非齐次二次型估计可容许的充要条件。
We prove that they are identical in the class of homogenous linear estimates, and get a necessary ann sufficient condition for their common admissible estimate.
并在较特殊的多元线性模型下，证明了这六种容许性在齐次线性估计类中是一致的，且得到了其共同的可容许估计的充要条件；
It is shown that URE is superior to least squares estimate, principal components estimate and combinatorial princ- pal components estimate under suitable conditions, and is admissible estimate.
在一定条件下，证明了此种估计优于最小二乘估计、主成份估计和组合主成分估计，且在均方误差意义下是可容许估计。
