1) According to an approximate estimate,
根据大约估计,
2) at the lowest computation
根据最低的估计
3) Basis of Estimate
估算根据
4) root power estimator
根方估计
1.
A new root power estimator ■(m_1,m_2) is proposed as to solving the problem that either or both of design matrixes A and B of growth curve model is/are likely to be ill-conditioned.
针对生长曲线模型中设计阵A与C至少有一个病态时的情况提出新根方估计■(m1,m2),并证明通过新根方参数mi(i=1,2)的适当选取,可使得该估计在均方误差意义下优于最小二乘估计及普通根方估计,证明其容许性及其对最小二乘估计抗干扰性的改进,并给出确定参数mi的两种方法。
5) root root estimator
根方估计
1.
In this paper, a new biased estimator called partial root root estimator is proposed through analyzing the corresponding properties of root root estimator, Stein shrunken estimator, and Sclove partial shrunken estimator.
在分析根方估计、Stein均匀压缩估计、Sclove部分压缩估计各自特点的基础上,提出了一种新的有偏估计部分根方估计,并讨论了它的优良性质。
2.
When the designed matrix is ill-conditioned, Covariance Adjustment Estimatorβ~ 1 is not accurate, so we propose a class of new estimators—root root estimator, which is based on the mean square error criterion.
因此本文在均方误差意义下提出了一类新的估计―根方估计。
6) restricted maximum likelihood estimation
约束的极大似然估计
