1·Proposes an algorithm of bi-iteration subspace tracking using instrumental variable, and it is a bi-iterate rank-one update model.

提出了一种运用辅助变量的双迭代子空间跟踪方法。

2·Through instrumental variable identification method, the single input single output difference equations and the Z transfer function were gotten.

采用辅助变量辨识方法辨识得到单输入单输出差分方程和Z传递函数。

3·The instrumental variable method and LILC criterion are used to estimate the order and parameter of electro-hydraulic position and force coupled system.

文中用辅助变量法和LILC定阶准则结合来估计电液位置和力偶系统的阶和参数，根据估计参数的渐近正态性确定模型的子阶和时滞。

4·The trick is to find an “instrumental variable” which can act as a proxy for one variable in a statistical analysis, but which is clearly unrelated to the others.

诀窍在于找到一种“工具性可变因素”，它能在统计分析中代替某种可变因素，但它显然与其他可变因素无关。

5·The instrumental variable in this instance allows a clear, credible estimate of the return from extra schooling for those most inclined to drop out from school early.

在这一研究中，对于那些倾向于尽早离开学校的人而言，使用辅助变量法就能够得出清晰可信的结果。

6·Mr Levitt’s analysis of crime during American election cycles, when police numbers rise for reasons unconnected to crime rates, is a celebrated example of an instrumental variable.

在本书中，Levitt对于美国大选期间犯罪率的分析（在此期间，警察数量的增长并非是由于犯罪率上升）是辅助变量分析的一个绝佳例子。

7·A new experimental procedure is proposed based on instrumental variable method for analyzing wall surface heat transfer process and deducing wall surface heat transfer coefficient.

首次提出了用辅助变量法分析建筑墙体外表面换热过程及推导墙体外表面换热系数的实验方法。

8·Then explained this paper institutions index's construction, instrumental variable, controlled variable's choice and various variables' data sources carries on showing on the paper.

然后说明了本文制度指标的构建、工具变量和控制变量的选择，并就文中各变量的数据来源进行说明。

9·Further, on this basis we derived an instrumental variable regression model. After disregarding the effect of multicollinearity among the explanatory variables, we verify the accuracy of the results.

并以此为基础，衍生出工具变量回归模型，在剔除了解释变量多重共线性的影响后，验证了结果的准确性。
