Abstract :
Based on transformation sinx, a new method for enhancing smooth degree of the standardized discrete data sequence is put forward. It is proved that the smooth degree of the standardized discrete data sequence can be greatly improved by using this transformation. Compared with logarithmic function method and power function method, the sinx function method can greatly improve the smooth degree. At last, the method is used to build model of population in China. The precision of the model is up to 99%, and the practical application results show the effectiveness of the proposed approach
