利用 SPSS 17.0 做因子分析,没有出结果,反而出现这样一段文字,
Warnings
There are fewer than two cases, at least one of the variables has zero variance, there is only one variable in the analysis, or correlation coefficients could not be computed for all pairs of variables. No further statistics will be computed.
请问这个是什么意思,我需要怎么取舍或增加数据才能做因子分析。谢谢!我是初学者,对统计知识只懂12,请麻烦说得详细些,劳驾了。
