The x2 test is lower , and the spearman rank correlation test is better than pearson test X ~ 2检验呈显著、极显著相关的种对数少于相关分析和秩相关分析, spearman秩相关分析优于pearson相关分析。
The spearman rank correlation test and kendall r rank correlation test are utilized to analyze the correlation of the typical implicit behaviors 采用spearman秩相关检验和kendall秩相关检验对典型的间接行为进行了相关性分析。
However , based on non - linear method , fmh depicts the facts of stock markets . secondly , this treatise summarize the methods of how to test the efficiency of stock markets , such as serial correlation test , run test , and filter test 本章首先阐述了文章的选题背景、选题意义以及选题目的;其次,分别综述了国外、国内研究动态;然后,总结了全文的研究思路和方法;最后,指出文章可能的创新之处。
Finally , using the correlation test of different exchange - rate returns , contagion evidence is found in 1997 - 98 east asia currency crises , and the portfolio model is employed to show the factors which result in currency crises contagion 最后,在研究货币危机传染问题时,通过对汇率变化率的相关系数的检验,发现了东亚97 98货币危机中传染的证据。此外,作者还用投资组合模型来解释了引起货币危机传染的几种因素。
By using serial correlation test and cross - section test through the data of the share companies that were listed in shanghai stock exchange before 16th oct 1998 , the size effects in china stock market was tested in the period from 16th oct 1998 to 26th oct 2001 . all the share companies which in total 373 were grouped into 11 according to four different criterions . these four different criterions were total circulating captal stocks , total circulating market value , total capital stocks , total value of a share company . through the correlation test between the abnormal return rate and the size of the group , no size effect was found through the size criterion of the total value and the total circulating value except only one period 运用序列相关性我国股票市场的小公司效应进行实证检验,所采用的样本是在1998年10月16日以前挂牌上市的373家上市公司从1998年10月16日到2001年10月26日,共150周的交易数据。对公司进行以规模大小分组时,分别采用了流通市值、流通股本、总市值和总股本四种不同的标准进行投资超额收益率规模相关性分析,发现以总市值和流通市值为规模标准的实证结果除个别时期内存在着小公司效应外,其它时期并不存在小公司效应,而以总股本和流通股本为标准的小公司效应最为明显;另外,小公司效应在统计区间内表现出时段性。
This paper includes five parts . the first is to review the study on the subject ; the second is to discuss the characteristic of chian ' s stock market . . the change of money - admitted policy and the questions on the study . the third is to verify the size effect in china ' s stock market by using correlation test and regression test on the bases of four different criterions , each criterion will be applied with two time - series methods . the fourth is to summary the main character of four different criterions , and apply joint test to the criterions that were proved the best concerning the size effect . the illiquidity risk was introduced to the study , the indexes of turn - over rate and the fluctuation of turn - over were used here . however , other factors that may influence the invest return rate as circulating rate and size were also included . according to the result , the size effect will be interpreted . the fifth is to summary the size effect and its explaination , and then to provide some useful invest strategies based on the conc lusion above 论文分五部分,第一部分对小公司效应的有关研究文献进行回顾;第二部分我国股票市场的状况、资金供给政策的变化和我国股票市场实证的相关问题进行论述;第三部分对我国股票市场的小公司效应按照四种不同的规模标准分类,每一种标准均分两种不同的统计周期分段标准进行实证分析;第四部分小结不同的规模分类、不同统计周期分段的统计结果特征,然后对小公司效应最明显的规模分类标准进行多因子联合回归分析,这里引入了流动性风险因素,其用换手率和换手率波动指标来衡量,还分别引入了其它影响投资收益率的因子,分别是规模、流通比例。
