摘要
文中编制了一个MATLAB程序,针对多个企业的基本数据进行主成分回归分析,得到一个经济效益的定量描述公式,从而可以不受人为因素制约地对企业进行综合评估并排名;分析发现企业经济效益主要由资金周转次数等因素决定,与实际情况相符,因此排名结果容易得到认同。此外还分析了指标间的关系。结果表明主成分回归分析法对于指标数多且指标间存在较大相关性的场合简洁高效。
In this paper a MATLAB program is designed for principal components regression analysis for basic data of several enterprises. A quantitative formula of economic benefits derived can be used to evaluate and compare economic results of enterprises without the influence of personal favor. The relationships between indexes are also discussed briefly. The results indicate that this regression method is simple and effective in the event that many dependent indexes exist.
