各位大侠,我遇到一个问题,用相关性分析的结果作为输入,做多维尺度分析时,没有二维图形出现,反而是下面一段话,我很不明白,不知道哪里出了错,也不知道怎么改进才会有图形出来。
Matrix 1 has 132 missing observations.
Iteration history for the 2 dimensional solution (in squared distances)
Young's S-stress formula 1 is used.
Iteration S-stress Improvement
0 .72979
>Error # 17227. Command name: ALSCAL
>ALSCAL is unable to calculate S-STRESS and will terminate prematurely.
>Possible reason is linear dependencies among specified variables.
>This command not executed.
1 .00000
Iterations stopped because
S-stress is less than .005000
