The determinants and productivity growth are analyzed by using regression techniques for limited dependent variable models with random effects 然后，运用虚拟因变量方法分析影响全要素生产率变化的具体因素。
Sometimes , it is useful to examine individual observations to see whether the actual value of the dependent variable is above or below the predicted value 有时，检验个体观测值来看它的因变量高于还是低于预测值是有用的。
Operational definition is accurate . it is expressed by operational way . it identifies that variables could be observable and measurable 操作性定义是指变量的较精确与不含糊的定义，将以操作的方式表示，标明因变量是能被觉察和测量的。
The research on the influencing factors is conducted in multivariate regression model , while the dea technical efficiency estimates are referred as dependent variable 本文进一步以技术效率为因变量，对影响银行效率的银行微观特征进行多元回归分析。
Regarding these factors as independent variable and abnormal return ( ar ) on announcement day as dependent variable , we establish a linear regression model 并选取适当的变量代表这些因素，以增发公告日股票的异常收益率为因变量，建立了多元线性回归模型。
Experimental design may not only clarify influence of the independent variable on the dependent variable in the testing , but also seek its best test condition 通过试验设计，不仅可以弄清楚试验过程中自变量对于因变量的影响的大小和趋势，还可以寻找其最佳试验条件。
On the basis of this characteristics of coefficients , two simple and effective methods , backfeed method and two - step estimation method , were given for estimation of the dependent variables in the model 基于这一系数特征，给出反馈和两步估计两种简单有效的方法，对模型中的因变量做了估计。
Hypothesis ( 3 ) : the experimental group will use less l1 - based strategies than the control group . hypothesis ( 4 ) : the experimental group will use more l2 - based strategies than the control group )实验中自变量是显隐性方法的差异(不用的策略训练方法) ，因变量是学生交际能力(效率) 。
It also compares the analytical results of multilevel models with the ols results to better understand the advantages of multilevel modeling technique 结果显示，普通模型过高地估计自变量对因变量的作用及影响程度；相反，多层模型调节数据的聚类性质，其参数估计更精确，得出的结论更符合实际。
