Finally, the fitness of Garman-Klass model and High-Low model estimators are twice efficient than historical volatility estimator.

In particular, for recurrent event data, we proposed a novel nonparametric estimator of the survival function and obtained an efficient estimator of the expected total number of events for counting processes. Also we established asymptotic properties of these estimators and investigated nonparametric estimation of survival functions, density functions and hazard functions under various types of incomplete data.

在重复事件发生的情况下，创新地提出了一种生存函数的非参数估计，获得了计数过程中预期事件总数的估计以及这些估计的大样本性质，并在其他各种不完全数据下对生存函数，概率密度和失效率函数等非参数估计进行了深刻研究。

Then the LS channel estimator obtained simply by space time block training sequence was projected to the signal subspace to get an estimator that was efficient but of low complexity.

在此基础上，对空时分组训练序列简单得到的LS信道估计器进行子空间投影，得到了复杂度较低同时性能良好的信道估计。

We propose a theoretical framework to predict the impact of inward FDI on the host country's incumbent firms' price-cost margins, according to the mode of entry of FDI We then investigate empirically the competitive discipline effect exerted by both imports and FDI on manufacturing plant-level price-cost margins in the UK, for the period 1991-2001. We estimate different specifications of the price-cost margin equation with both fixed-effects instrumental panel estimator and efficient generalized method of moments estimator with clustering correction.

通过构建理论模型预测FDI的不同进入模式对东道国企业价格－成本盈余(Price-Cost Mar-gin， PCM)的影响，以及采用固定效应工具面板和经过聚类修正的有效广义矩等不同估计模型，对1991-2001年间的进口和FDI对英国制造业企业PCM竞争规制效应进行的实证研究表明：绿地FDI对利润有负向影响，而并购FDI对利润的影响为正，即绿地FDI对PCM有规制效应，并购FDI会增加PCM。

I plant adhere to an efficient point, line and plane mode of operation of the market network.

我厂坚持高效率的点、线、面的市场网络经营方式。
