查询词典 analytic function of several variables

The researchmethodology system is as follows:The variables that can be measured and have significance to stock relative intrinsic value are industry characteristic, profitability,development potential,qulity of earing and asset, the expandable potential of capital stock,the ability to pay off the debt,asset manging ability and the scale of the capital stock;(2)When the MFPM is established, the original variables should be disposed beforehand;(3)As for the research objects.we should value synthesizationly the achievement of the listed,and take the No.

本章所建立的研究方法体系为：（1）上市公司个股基本面因素中可以量化，并且对股票相对内在价值有重要影响的主要有行业特性、盈利能力、成长性、盈利质量及资产质量、股本扩张潜力、偿债能力、资产运营效率和股本规模大小等方面；（2）在建立MFPM模型时，原始指标值是不能直接用于模型计算的，必须对数据进行预处理后才能用于模型中：（3）在确定研究对象时，需要对上市公司经营绩效进行综合评价，在剔除主要靠未来业绩预期定价的第Ⅳ类股后，把第Ⅰ、Ⅱ和Ⅲ殴作为模型研究对象；（4）在选择多元回归模型时，由于原始自变量由于存在错综复杂的关系，尽管对原始自变量进行过预处理，但自变量指标依然会存在一定的多重共线性，为此在建立MFPM模型时，须采用逐步回归模型；（5）在检验MFPM模型有效性时，须从统计意义和投资实战意义两个方面进行。
