| Abstract: | Two synthetic indices are constructed by Non Linear Principal Component Analysis for 5 signs of aging and 13 diseases respectively. The relationships between two synthetic indices?gender and age are showed quantitatively. The results show that there are not any correlation between the signs of aging and diseases, but difference of gender on signs of aging is significant, some differences on gender and age are very interested. |
