程序运行出来，怎么判断出双因子的结论最合适。
以下是程序：
DATA ECON;
     TITLE 'Four Socioeconomic Variables';
     TITLE 'Modern Fctor Analysis';
     INPUT assets debt turnover profits;
     CARDS;
4.89   32.35   1.99    7.07
17.56  60.12   2.59    13.15
10.62  63.84   2.33    5.74
12.12  43.56   2.19    8.26
12.74  57.58   2.59    5.78

PROC FACTOR DATA=SOCECON METHOD=ML HEYWOOD N=1;
     TITLE3 'Maximun-Likelihood Factor Analysis with One Factor';
PROC FACTOR DATA=SOCECON METHOD=ML HEYWOOD N=2;
     TITLE3 'Maximun-Likelihood Factor Analysis with Two Factors';
PROC FACTOR DATA=SOCECON METHOD=ML HEYWOOD N=3;
     TITLE3 'Maximun-Likelihood Factor Analysis with Three Factors';
RUN;
结果太多，大侠们可以运行一下看看。帮我解答解答，O(∩_∩)O谢谢
