Research on gompertz curve model used for mobile user growth

This paper deals with the application of gompertz curve model to mobile user growth. gompertz growth curve is a kind of product life cycle theories, which reveals the development of product markets has a sigmoid growing process. The gompertz curve model which can be transformed, employ ordinary least-squares principle to simply formula. Based on historical data, the initial formula can be projected. In order to achieve better prediction accuracy,0.618 optimal seeking methods can be employed to optimize Model ,which adjusts limit parameters of gompertz growth curve for the purpose of fitting actual data. Although the gompertz model establishment for Postal and Telecommunication Services is demonstrated in this paper, this model can be applied in many fields. Example programs for specifying these models based on the use of the gompertz Curve Model are also provided. So the gompertz model is effective path to the research of product life cycle theories, which the prospect of application will be promising.
