However , after the actual survey , a factor analysis conducted on the items could not confirm the initial conceptual dimensions , instead , seven orthogonal factors with 48 items were extracted as follows 但是,在實(shí)際調(diào)查之后,根據(jù)上述項(xiàng)目而進(jìn)行的因子分析不能肯定原先的概念向度,反而得出七個(gè)正交因子,總共48個(gè)項(xiàng)目,詳列如下:
In chapter one , we argue about how to choose factors with influence stock market results , build orthogonal factor model and give the factors meaning of matrix . in addition , we improve apt in three ways . firstly quote suppositional variable , which makes apt in consistent with the economic objectivity in reality 同時(shí),對(duì)原有的apt模型的作了以下改進(jìn): ( 1 )引入虛擬變量,這是因?yàn)榭紤]到股票市場(chǎng)上的人為地、不確定的因素較多,譬如交易規(guī)則的顯著變化、證券法的實(shí)施等,這樣引入虛擬變量可以使apt與現(xiàn)實(shí)經(jīng)濟(jì)的客觀性相符。
