我想问:相关系数矩阵不是个因素之间的相关性么,如何用来命名?
主成分表达式为:F1=0.356545123352007ZX1+0.249798824659015ZX2+0.352822052837537ZX3+0.3875813282191ZX4+0.395206468554044ZX5+0.402018370525538ZX6+0.247232531435982ZX7+0.396033569076207ZX8
F2=-0.385813683740678ZX1+0.607830864802339ZX2+0.00734901463162658ZX3-0.100126232856301ZX4-0.22150300049348ZX5-0.0802802836108441ZX6+0.643568532627671ZX7-0.0438316243738089ZX8
