| Abstract: | Surveys were made in six successive years of the population of Rattus nitidus. Analysis of the data showed that its population density in June and October was associated with the population density, Sexual ratio and age structure of the animal in the spring (January to March) of the previous year. Mathematical models of linear regression, stepwise regression and fuzzy correlation were established, of which fuzzy correlation model fitted the original data best and is recommended in the forecasting of the fluctuation of the population density of R.nitidus. |
| Keywords: | Rattus nitidus Hodgson predictions fuzzy models regression analysis |
