关于spss因子分析法计算总综合得分F的方法.
一、spss中的因子分析,究竟哪个是方差贡献率(是用extraction sums of squared loadings的数据,还是rotation sums of squared loadings的数据),用以计算综合得分F呢?而公式是怎样的?
二、为什么有的案例中计算综合得分的公式不用除以累计贡献率(该题中的67.207%),而有的案例则需要除?
该题中究竟是用公式F=39.229%×F1/(67.207%)+9.332%×F2/
(67.207%).2.003%×F8/(67.207%),
还是F=320.525%×F1/(67.207%)+11.291%×F2/(67.207%).2.587%×F8/(67.207%)
三、 component plot in rotated space(旋转空间因子图)图有什么作用?
(不知图片清楚不,再附上Extraction Sums of Squared Loadings 和\x05Rotation Sums of Squared Loadings的数据)

要除以累计贡献率.至于用哪一个,要看你做因子还是主成份提取,前者用旋转后的方差贡献率,后者用提取的方差贡献率.
