Futures price is the unbiased estimate of expected spot price , which is based on the function of risk transferring 期货价格是未来现货价格的无偏估计，这是建立在风险转移功能基础之上的。
Based on wavelet analysis , wls is the best linear unbiased estimator of regression model parameters in the context of l / f noise 基于小波技术的wls法是具有1 f噪声的系统回归模型参数的最佳线性无偏估计。
Unbiased estimators are not necessarily consistent , but those whose variances shrink to zero as the sample size grows are consistent 无偏估计量未必是一致的，但是那些当样本容量增大时方差会收缩到零的无偏估计量是一致的。
The proposed method can provide unbiased estimate of the ms ' s position . it is characterized by high efficiency and small memory volume requirement 该方法对移动台位置的估计是一种无偏估计，具有存储量小、摘要定位效率高的特点。
If we are presented with an estimator that is both linear and unbiased , then we know that the variance of this estimator is at least as large as that from ols 如果有人向我们提出一个线性无偏估计量，那我们就知道，此估计量的方差至少和ols估计量的方差一样大。
The unbiased predicted value or estimated value of gene main effects and gene treatment interaction can be used as precursor to clustering to make sure the inputs are statistically meaningful and of biological interest 对基因主效应的无偏估计值和基因与处理互作效应的无偏预测值进行聚类可以获得具有统计学和生物学意义的结果。
The results indicate that if all the investors all full rational , the equilibrium price , whether using close call auction or open call auction , is the unbiased estimator of the risky assets true value 研究结论表明，若所有的投资者都是理性的，无论采用封闭式集合竞价还是开放式集合竞价，那么均衡价格均是风险资产真实价值的无偏估计量。
Abstract : based on signal processing theory about high - order cumulants ( hoc ) , a fast , inexpensive and unbiased cumulants estimation approach is proposed for the detection of multifrequency signals between offices connected to telephone networks 文摘:基于高阶累积量的信号处理理论，提出了一种快速、简便且无偏估计的方法对多频信号进行有效的检测。
A verification technique , which obtains unbiased estimator for the means and variance of several global and local features is presented and a matching way after acquiring the threshold by probability density function is achieved 摘要论述了在获得在线手写签名的曲线的一些局部和全局特征的平均值和方差的无偏估计的基础上，通过概率密度函数进而获取阈值进行匹配的鉴别方法。
Enlightened by the idea of aic , this paper treats the data of the same group as samples of certain distribution . in this way , it determines the number of groups by seeking the asymptotically unbiased estimate of kullback - leibler information 在aic准则思想的启发下，将应该同属于一个分类的数据看作是在某一分布中抽取的样本，从而通过求kullback - leibler信息量的渐近无偏估计而达到确定类数与数据分类的目的。
