渐近无偏性 meaning in Chinese
asymptotic unbiasedness
Examples
- 2 ) the concept of space frequency distribution is introduced into reevaluation of incoherently distributed source model . based on the model , two low - complexity robust bearing estimators are developed . it is proved theoretically that their estimates are asymptotically unbiased and consistent
2 )从空间频率分布的角度重新评价了非相干分布源模型，提出了两种低计算复杂度的稳健的分布源波达方向估计器，并从理论上证明了它们的渐近无偏性和渐近一致性。 - This paper studies mainly the theories of the semi - parametric regression model : ( 1 ) under proper conditions , using random weighted way to the estimator of the error density f ( x ) of the semi - parametric regression model , this paper proved the strong and weak consistent and the asymptotic unbiased property of the weighted kernel estimation fn1 ( x ) of the f ( x )
本文对半参数回归模型：主要做了以下三个方面的理论研究： ( 1 )将随机加权法应用到半参数回归模型的误差密度f ( x )的估计当中去，在适当的条件下，证明了误差密度的加权核估计( ? ) _ ( n1 ) ( x )的强相合性、弱相合性及渐近无偏性。 - In this paper , we utilized the wavelet to estimate cook ' s , friedman ' s and hall ' s projection index , and proved that the wavelet estimator of this projection pursuit indices are mse convergence and asymptotically unbiased . , and the wavelet estimator of the ppda index is asymptotically unbiased
