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。
Because the dependent variable in the models is the share of consumption of food , and the models are equation of demand system , therefore , zellner s seemingly unrelated regression method is applied to estimate the models 因为在模型中作为因变量的是食物的消费份额,同时模型是需求系统方程,因而,采用近乎非相关的系统迭代回归法进行模型估计。
Finally , it chose some influential factors to soybean futures price as variable and built up its multi - regressive model so that we can explain the cause of formation . it also did a further study on the variables in the model by factor analysis 最后选择对大商所大豆期货价格有影响的因素作为变量,建立大商所大豆期货价格形成的多元回归模型,以便对大商所大豆期货价格形成机制作出适当的解释,并应用因子分析方法对回归模型中的变量作进一步的分析。
On considering of the economic situation , under which the economy of our country will be continually located in the phase of powerful policy guidance in a long time , the capital construction investment and government budget expenditure are taken as two exogenous policy variables in the model 该模型是以基本建设投资和财政支出为政策性外生变量。之所以这样,是因为我国经济在将来一个较长的时间内仍将处于较强的政策干预阶段,经济的发展方向和增长速度均服从于国家各重要政策。
