摘要:
对上海深圳交易所1998~2002年1 100余家公司5 571份年报12个财务比率的综合研究揭示,绝大多数财务比率不服从正态分布且不易变换到接近正态。正态变换实证过程表明:原始财务比率数据经行业划分、剔除污染样本后再进行Box-Cox变换的的正态变换效率最高,可使绝大多数财务比率接近正态分布,但仍有少数比率无法正态化。
Abstract:
Based on the research of 12 financial ratios of more than 5 571 annual reports from 1 100 listed companies (Shanghai Stock Exchange and Shenzhen Stock Exchange) in the years of 1998~ 2002, this paper concludes that most of the financial ratios are not normal distribution and the level of normality can be highly promoted through data cleaning and data transformation ( such as Box-Cox transformat ion) on the basis of the industry samples. The normal transformation process shows that a few financial ratios can not be normalized.
