查询词典 linear operator

In statistical analysis of ordinal data, we usually build up linear-by-linear association model and meet a trouble of choice of scores. Graubards et a1 (1987) proposed several methods for score choice in independence test in ordinal 2×κ contingency tables: equally spaced scores, midpoint scores and midrank scores. He also pointed out that the result of independence test may be different for the different choice of scores according to the same association model. Agresti et a1 (1987) treated the score vector in row effects and column effects model for two-way contingency tables as parameters and derived the necessary and sufficient condition of the solution under monotone order restriction by Kuhn- Tucker conditions.

在有序数据的统计分析中，通常要建立线线相关模型，其中得分的选取是一个棘手的问题，Graubard et a1（1987）给出了有序2×κ列联表中独立性检验的几种得分选取方法：等距离得分，中点得分和midrank得分等，同时指出，对于同一个相关模型，独立性的检验会由于得分选取的不同而得到不同的结论，Agresti et al（1987）把二维列联表中的行效应和列效应模型中的得分向量作为参数，在满足递增的序关系情况下，利用Kuhn-Tucker条件给出了解的充要条件。

The experiment was divided into two parts: linear guidance and waypoint guidance by satellite. In order to get a better result for linear guidance, the four parameters "rud","ctr","yau", and "trn" of the Pilot model for Autopilot were properly selected. Here, the GPS receiver was used only for collection of satellite signals and storage of data.

实验分为自线导航与卫星导航两部分：在直线导航中，修改自动导航器Pilot模式下的rud、ctr、yau和trn四个参数，藉以找出直线行进时较理想的状况，此时的GPS接收机仅做为接收卫星讯号并记录之用。

There are four innovations in this paper: firstly, in order to focus our research on the development of matured stock market, we use the data in 2007 as our sample interval, which makes the results of the model more convincing. Secondly, taking the potential non-linear relationship among the various of indexes fully into account, we employ cointegration test instead of using the multiple variables linear regression method to study stock price index and macroeconomy.
