| Abstract: |
| Qualitative analysis was conducted on the impact factors of price of traditional Chinese medicine Siraitia grosvenorii, and then the price series of Siraitia grosvenorii was modeled using the GM (1, 1) model, of which fitting precision and higher accuracy were studied by the gray system theory. The results showed that the samples length of 4 GM (1, 1) model has a good prediction ability for the quarterly average price of Siraitia grosvenorii. |
| Key words: price prediction GM (1,1) model Siraitia grosvenorii |
