* Parallel Analysis Program For Raw Data and Data Permutations.* To run this program you need to first specify the data for analysis and then RUN, all at once, the commands from the MATRIX statement to the END MATRIX statement.* This program conducts parallel analyses on data files in which the rows of the data matrix are cases/individuals and the columns are variables; Data are read/entered into the program using the GET command (see the GET command below); The GET command reads an SPSS data file, which can be either the current, active SPSS data file or a previously saved data file; A valid filename/location must be specified on the GET command; A subset of variables for the analyses can be specified by using the "/ VAR =" subcommand with the GET statement; There can be no missing values.问题1:链接里说需要使用“GET命令”运行矩阵,请问SPSS中要到哪里输入GET命令啊?谢谢大神相助!
另外还想讨论一个问题。现在探索性因子分析一般都是使用特征值大于1和碎石图的方法来判断公因子数目,但特征值法只能应用于主成分分析,碎石图法存在主观性,个人感觉平行分析本身的假设(基于实践数据得出的因子特征值大于随机高百分位数因子特征值)和适用性均要优于前面两种方法。可是为什么国内研究几乎很少见到平行分析?平行分析的局限有哪些呢?
