Linear mixed model is a kind of linear models , which includes both fixed effects and random effects . it is frequently used in biology , medicine , economics , determining , sampling designs and quality control procedures , and so on 线性混合模型是既包含固定效应又包含随机效应的一类线性模型,它被频繁的应用于生物、医学、经济、抽样设计和质量控制等过程。
Results there are two important data analysis strategies for comparing the different effects between the two treatment groups : ( 1 ) fixed effects model , such as independent t test , analysis of variance and analysis of covariance ; ( 2 ) linear mixed models 结果临床试验研究资料常为重复测量资料,比较各处理组的测量值差别是否有显著性,可以采用传统的统计方法如t检验、方差分析和协方差分析等;也可以采用混合模型对整个研究过程中所有时点的测量值进行分析。
The variable intercept fixed effect panel data model set up in this paper based on the financial data between 1997 and 2004 of 34 listed companies in electric power industry has proved that the theoretical analysis of this paper is well founded in that the maturity structure of debt financing has remarkable positive relation with enterprise value ; and that the size of enterprises , the ratio of negotiable share and the shareholding ratio of the first shareholder have significant influence on enterprise value 本文利用34家电力行业上市公司1997 ~ 2004年的财务数据,通过建立变截距固定效应面板模型,证明企业价值与债权融资期限结构具有显著的正相关关系,这一结果支持了本文的理论分析;实证结果还表明企业规模、流通股比例、第一大股东持股比例对企业价值具有显著的影响。
Part two introduces the theory of panel data . the basic form of panel data is : yi t = it + xi t it + uit , i = 1 , 2 , … , n ; t = 1 , 2 , … , t panel data is used for describing the instance of swatch in a collectivity in some time , and observing every unit in swatch multi - scale . basing on the different hypothesis of ui , panel data has fixed effect model and random effect model , if ui is a unit constant ( corresponding to the dummy variable of 基于分析结果,本文给出了改革我国公司治理结构的若干建议: ( 1 )股权性质方面,培育有效的国家股持股主体; ( 2 )股权结构方面,逐渐调整股权结构,减少第一大股东持股比例,增加除第一大股东以外的大股东的股权集中度; ( 3 )董事会方面,采取奇数型董事会规模,并完善独立董事的生成机制; ( 4 )激励制度方面,应加大董事及总经理的持股比例。
As far as the general mixed - linear model is concerned , this paper explores the two - staged prediction of the linear combination about the fixed effects , and the random effects and meanwhile an approximate computation formula is derived for the mean square error of the two - staged prediction which paves the way for comparing and contrasting the advantages and disadvantages of different variance components 摘要对一般的线性混合模型,研究其固定效应与随机效应线性组合的两步预测问题,给出了两步预测均方误差的一个近似计算公式,为比较不同方差分量估计的优劣性进一步奠定了基础。
The evidence from the regression of multiple and fixed effects model demonstrates that funds ’ abnormal return of last year , depreciation rate , unit net asset and fund manager ’ s working experience have close relationship with fund performance , aomg which , the former three factors have positive relation 通过多元固定影响模型的回归分析证实,基金上一年度超额收益、折价率、单位净资产以及基金经理从业经历与基金绩效密切相关。在基金上一年度超额收益越多、折价率越高、单位净资产越多的情况下,基金经理越有可能采取积极投资策略,选择更加优化的投资组合,赢得更好的投资组合收益。
