查询词典 sufficient statistic

Further more, most analysis lacks sufficient statistic data as a strong support.Most of the analysis refer to or directly quote other foreign works and therefore the conclusions are less practical and convictive.

尤其重要的是，由于我国对雇员流动的数据统计资料不足，这些分析大多参照或引用国外同行资料得出，因而其结论实用性、说服性不强。

It is shown that if the distribution of market information is equal, then the equilibrium price serves as a sufficient statistic for the market information.

研究中特别将私人讯息分配之情形纳入模型中，并假设投资人之绝对风险厌系为常，各自追求预期效用极大，得出市场结清均衡时，均衡价格为市场讯息按照其精确与观察频之乘积加权平均。

When all the market information frequencies are proportional to the information observed, the equilibrium price is a sufficient statistic for market information.

Fortunately, crude monetarism has not been proposed as an elixir for deflation in the rest of the world -- yet. Much of the academic community recognizes De Long's distinction between Old Chicago Monetarism, which did not believe velocity to be stable or money supply control to be straightforward or easy, and Political Monetarism, which argued that velocity is stable and that money supply is a sufficient statistic for controlling nominal demand.

幸运的是，世界其他地区还没有把拙劣的货币主义当作治疗通货紧缩的灵丹妙药----至少到目前为止尚未如此。

We posed the concept of sufficient intersection about s(1≤s≤n) algebraic hypersurfaces in n-dimensional space and proved the dimension of polynomial space Pm(which denotes the space of all multivariate polynomials of total degree≤m) on the algebraic manifold S=s(f1,…, fs) where f1(X=0,…, f s=0denote s algebraic hypersurfaces of sufficient intersection, then gave a convenient expression for dimension calculation by using the backw ard difference operator.

Paper studies the practical stability of electricity market models by tools, for example, the appropriate structure Lyapunov functions, Cauchy matrix, the matrix measure, constant variation. Judging practical stability sufficient conditions and estimating formula of ultimate convergence boundary are provided. Conditions are descriptive by coefficients of models. At the same time, paper studies the Lyapunov stability of the electricity market. As well as the sufficient conditions of judging electricity market Lyapunov stability are provided. Some of conclusions improved the results of Alvarado and others. The conclusion of Lyapunov stability has made a comparative with practical results.

首次将实用稳定性理论和方法应用于电力市场稳定性的研究中，借助于构造合适的Lyapunov函数、柯西矩阵、矩阵测度、常数变易法等工具，系统研究了所建电力市场模型的实用稳定性，得到了用模型的系数来描述其实用稳定性的一系列判定条件和最终收敛边界的估计公式；同时对电力市场的Lyapunov稳定性进行了研究，得到了电力市场稳定性的若干判据，部分结论改进了Alvarado等人的结果；随后将Lyapunov稳定的结果与实用稳定进行了比较。

Only one complete corollinae chromosome was detected in Ml4, and was determined corollinae chromosome 9. We have used in situ hybridization of genomic DNA to discrimination the parental chromosomes in Beta Ml 4, suppression of cross-hybridization by blocking DNA was not necessary indicating that the investigated Beta genome contain sufficient species-species DNA enabling the unequivocal determination of genomic composition of the hybrids.In our study , the results of BAC -FISH combined with the analysis of GISH in Beta M14,indicating that present of the corollinae chromosome 9 alone was sufficient to confer apospory in Beta M14 upon celluar and molecular..
