| Abstract: | To analyze the defect of the existing GM (1,1) model and discrete GM (1,1) model,the direct discrete GM (1,1) model of colleges and universities enrollment was built. For a case study,the predicted results shown that direct discrete GM (1,1) model has better forecasting precision,and it is more close to the enrollment growth trend. |
