Prediction model based on Gompertz function

A novel prediction model based on Gompertz function and customer life cycle (CLC) is presented in this paper. Firstly, the calling behavior between the inner-net (China Unicom) mobile customers and the outer-net (China Mobile) mobile customers are extracted and analyzed, then fitted a CLC curve by Gompertz function. Furthermore, the different period of CLC is identified according to the fitting curve. Finally the number of outer-net mobile customers is predicted accurately and dynamically. The experiments of real data illustrate the availability and accuracy of the proposed prediction model.
