-
摘要: 根据北京师范大学1991~1995年学生HBsAg阳性率,利用灰色模型和移动平均法,给出预报男生和女生阳性率的预报模型,对1996年学生阳性率进行预测,预报男生阳性率的相对误差为6.78%,女生为15.37%。Abstract: According to the students' positive rates of HBsAg,the grey model and moving average method were conducted for the dynamic models of HBsAg in Beijing Normal University in 1991-1995.Forecasting results:the relative errors of the positive rate were 6.78% in boy undergraduates and 15.37% in girls respectively in 1996.
