最优性判别 meaning in Chinese
optimality criterion
Examples
- Based on the least squares and biased estimation especially ridge estimation , a new estimation , that is , generalized ridge estimation is put forward through studies on restriction of the parameter . model ' s prediction being considered , comparison of superiority of optimal and classical predictions with respect to the ridge estimation is showed . regression diagnoses especially distance for principal components estimation is discussed
论文基于最小二乘估计及有偏估计特别是岭估计，对参数的约束条件做了进一步研究，并提出一种新型估计即广义岭型估计；对模型的点预测问题进行深入探索，得出一种基于岭估计关于经典预测和最优预测的最优性判别条件；也对回归诊断特别是基于主成分估计的距离进行了深入探讨。 - In term of the prediction problem , the fourth chapter discusses its superiority of the optimal and classical predictors based on the ridge estimation , and gives an necessary and sufficient condition of comparison of its superiority under the condition of criterion by some properties of partial ordering of matrix
借助矩阵中l ? wner偏序的一些性质，获得在此判别准则下判别两类预测量最优性的充要条件。为研究基于有偏估计关于两类预测量的最优性判别问题提供了一种方法和思路。
