根据内蒙古鄂尔多斯荒漠草原1975～1989年鼠疫疫区资料,利用多元回归分析,给出预报长爪沙鼠鼠疫流行的数学模型,拟合率为84.6%。在此基础上,得到了多元曲线回归的预测模型,拟合率为100%。
According to the plague epidemic area data of Ordos desert grassland from 1975 to 1989 in Inner Mongolia, the mathematical model for forecasting the epidemic of the gerbil Meriones unguiculatus was given using multiple regression analysis, and the fitting rate was 84.6%. On this basis, the prediction model of multivariate curve regression is obtained, and the fitting rate is 100%.
